In my earlier column, The Sounds of Yesteryear (Half 1), we explored a few of the ingenious methods people have devised to retailer and reproduce audio content material, with a concentrate on music. Particularly, we mentioned magnetic wire units, which recorded sound indicators on metal wires. These little scamps predated magnetic tape recorders.
As an apart, I’ve a ardour for science fiction. One of many books I usually advocate to like-minded buddies is A Fireplace Upon the Deep by the American writer and professor Vernor Vinge. This begins with an expedition from a younger human civilization on the fringes of the Milky Manner. They’re investigating a newly found information archive on an historical and uninhabited planet. Suffice it to say that they awaken a malignant super-intelligence, after which issues go quickly downhill. All this takes place within the first couple of pages — you wouldn’t imagine what occurs subsequent!
The rationale I point out historical information archives right here is that a lot of the know-how I grew up with is now however a distant echo of a reminiscence within the collective consciousness. For instance, many younger individuals have by no means even heard of things like 4-track and 8-track cartridges and their corresponding gamers. Does this lack of understanding actually matter within the scheme of issues? In all probability not, however it makes me unhappy to know that we neglect issues so rapidly. Alternatively, now that a lot information (together with this column) is being captured in digital kind, it could present fodder for historians 1000’s of years therefore. (If you’re such a historian, then could I bid you a cheery “Good day”?)
We’ll return to 4-track and 8-track methods momentarily, however first, to set the scene, let’s kick off with disk recordings. Early information circa the 1900s are sometimes known as “shellac information” as a result of they had been constructed from a pure resin known as shellac. These had been brittle and heavy, and — simply to extend the enjoyable and frivolity — they had been produced in quite a lot of speeds starting from 60 to 130 revolutions per minute (rpm) and sizes starting from 7 to 12 inches in diameter. By 1912, the trade had largely standardized on 78 rpm and 10- or 12-inch diameters, which may maintain roughly 3 to five minutes per aspect.
In 1948, Columbia Data launched 33⅓ rpm LP (Lengthy Play) information, constructed from vinyl, which was lighter and extra sturdy than shellac. These 12-inch information may maintain as much as 22–25 minutes per aspect, making them superb for classical music and full albums. In 1949, RCA Victor launched 45 rpm 7-inch disks, designed for single songs or prolonged performs (EPs). These had been cheaper to supply and buy, making them superb for pop hits and jukeboxes.
Data previous to the Nineteen Fifties had been monophonic (mono), which implies they supported solely a single audio channel. Stereophonic sound (stereo), which helps two separate audio channels (left and proper), grew to become mainstream within the Nineteen Fifties. The way in which through which two channels might be encoded utilizing a single groove in a vinyl document is (a) a tribute to the ingenuity of mid-twentieth-century engineers and (b) a narrative for an additional day.
As one other apart (I merely can not assist myself), in 1973, the UK comedy group Monty Python launched their fourth document album, titled The Monty Python Matching Tie and Handkerchief. The primary aspect of this document had a single groove as traditional. Nevertheless, the second aspect had two concentric grooves. This meant that, relying on the place the stylus landed if you set the document operating, you’d hear certainly one of two fully completely different units of sketches — primarily giving the album a hidden “third aspect.”
Many unsuspecting followers thought their copy was faulty or that they’d imagined lacking materials till they found this dual-groove gimmick. I bear in mind my buddies and I falling for this trick ourselves. When certainly one of our quantity first received this album, we instantly gathered at his home and performed either side. Then some extra buddies arrived, so we performed either side once more. By probability, the second taking part in of the second aspect ended up on the choice monitor, leaving these of us who had been there from the beginning with very puzzled expressions on our faces.
I wager there are some individuals who, by random probability, ended up listening to the identical monitor on the second aspect a number of instances earlier than finally touchdown on the hidden monitor. I generally marvel if there may be somebody on the market who has at all times landed on the identical monitor and — to this present day — has no concept that there are two tracks on the second aspect of their copy of this album.
Let’s change monitor (no pun supposed). As automobile possession boomed within the Nineteen Fifties and Sixties, individuals spent extra time commuting and touring by vehicle. Though radios had been frequent in automobiles by that point, they didn’t provide management over what was performed. Drivers needed the power to decide on their very own music, a functionality that radios couldn’t present.
The requirement was for a compact, sturdy, and easy-to-use music system that would face up to the vibrations and temperature modifications inside a automobile. Moveable document gamers weren’t actually an choice, though some individuals tried (bless their little cotton socks). In 1962, the American businessman and engineer Earl William “Madman” Munz created the Muntz Stereo-Pak, higher often known as the 4-track cartridge, through which the tape shaped an countless loop. Muntz licensed in style music albums from document firms and duplicated them on these 4-track cartridges (first marketed as “CARtridges”).
In 1964, William Powell Lear (the identical Invoice Lear who based Lear Jet) led a consortium that took the 4-track idea and prolonged it into the 8-track cartridge and participant system. The mainstream utilization mannequin targeted on taking part in pre-recorded music. Though it was technically attainable for customers to document their very own 8-tracks utilizing specialised tools, this was unusual in apply.

As for 4-track units, the best way 8-track methods labored was… let’s say fascinating. On this case, the tracks had been divided into 4 pairs of stereo channels. The tapes had been recorded on an ordinary 8-track reel-to-reel recorder. Nevertheless, when the tapes had been loaded into an 8-track cartridge, the tape ends had been spliced collectively to kind a steady loop (see an image on Wikipedia).
A twin playback head was used to learn two tracks concurrently. A small piece of metallic foil was connected on the splice level. When this foil handed below a sensor, it triggered the playback head to shift to the following pair of tracks. Navigation was extraordinarily restricted: most 8-track gamers didn’t have a rewind operate, and lots of didn’t also have a fast-forward functionality. Nevertheless, nearly all 8-track gamers had a button to manually advance to the following program — that’s, the following of the 4 stereo pairs.
In 1965, Ford grew to become the primary automaker to supply 8-track gamers as a manufacturing facility choice, debuting in choose 1966 fashions. By the late Sixties and Seventies, 8-tracks had turn into extraordinarily in style, particularly in automobiles, the place their continuous-loop design made them notably handy. In truth, circa 1975 to 1978, 8-tracks and vinyl LPs had been neck and neck in gross sales.
Unhappy to narrate, nonetheless, the writing was on the wall. Because the Seventies drew to an in depth, the Compact Cassette started to realize floor. Smaller and extra moveable, compact cassettes had been all the pieces 8-tracks weren’t. They had been simpler to retailer, didn’t endure from abrupt program modifications, and might be rewound or fast-forwarded with precision. By the early Nineteen Eighties, compact cassettes had not solely dethroned the 8-track however had been beginning to problem vinyl information.
I by no means owned an 8-track system myself, however a number of of my older cousins did. They started by assembling their collections of 33⅓ rpm 12-inch and 45 rpm 7-inch vinyl information within the late Sixties. After which they repurchased most of those titles on 8-track cartridges within the early Seventies so they may play this music of their automobiles. I don’t bear in mind them being overly involved by this. What I do recall is that they had been considerably disgruntled once they needed to buy all the pieces once more on compact cassette tapes as this format gained prominence. I additionally recall them being a mite miffed (one may maybe say “peeved”) when compact cassettes had been displaced of their flip by compact discs (CDs).
In my earlier column, we famous that streaming now accounts for ~85-90% of all music income, whereas bodily media (vinyl, compact cassettes, and CDs) account for 7-10%, and downloads (digital gross sales) account for less than 3-5%.
At first look, this would appear logical. It’s straightforward to know the development from vinyl to 4-track to 8-track to compact cassette to CD to MP3 downloads to streaming. What’s considerably shocking is the present resurgence in bodily media.
Vinyl started making a comeback within the mid-2000s, pushed by nostalgia, audiophile appreciation for the heat of analog sound, and a need for tangible music possession. By 2020, for the primary time in many years, vinyl even outsold CDs within the U.S. The format’s giant paintings, collectability, and affiliation with indie and hipster tradition helped cement its return as a beloved area of interest — now surprisingly mainstream once more.
Though far much less dramatic than vinyl’s revival, compact cassettes started to reappear within the late 2010s. Pushed by retro aesthetics, indie music scenes, and DIY attraction, cassettes provide a reasonable, bodily format with appeal. Restricted-edition releases and classic Walkmans add to the nostalgia, although the comeback stays largely underground and collector-focused.
In the meantime, compact discs have additionally skilled a modest resurgence because the early 2020s. Though streaming dominates, some listeners are returning to CDs for his or her affordability, wonderful uncompressed sound high quality, and sense of possession. Particular-edition releases and secondhand bargains have additional contributed to their quiet however rising attraction.
All I can say is, “Who would have thunk?” But it surely’s not all about me (it ought to be, however it’s not). What say you?
