Great comments, everyone! It’s funny how there is a lot of micro-history that doesn’t necessarily make it into the history books.
A few more things from me…
I find it hard to imagine that an adult with any interest in music would not have heard of CDs by, say, the end of 1984, as record stores were giving them small but prominent space by then IIRC. Certainly by sometime in 1985 they were quite visible in your basic music chains like Camelot. Plus, they were new tech and getting considerable press.
My best friend (then and now) and I sneered CDs. We were vinyl guys, but, moreover, CDs were pricey. A new vinyl record cost $10-12 in 84/85, but CDs started out at $19.95 IIRC. One thing that pissed us off was that the quality of vinyl pressings by the majors was deteriorating quite noticeably. I got the Shriekback album Oil & Gold when it came out in 1985, and it was just lousy with skips. I returned it to the store, and the next one was just as bad. I think I returned that one too and just gave up.
It started to get hard to get new releases on vinyl around 1990 or so. I remember feeling thrilled to find Poison by Bel Biv Devoe in 1991 on vinyl.
I bit the CD bullet in 1992 when I went to Japan. Vinyl died much sooner there than in the US. CDs were it by the mid to late 80s. CDs were still pricey in Japan, but a vast industry had sprung up of stores renting CDs so that you could copy the songs you wanted on cassette. I bought Beatles CDs and a lot of blues discs that I still have today.
In terms of their use in data, yeah, it’s easy to forget how recently that became common. When I went to grad school in 1998, we were all using 3.25" floppies in the computer lab. There was no CD capability and, needless to say, no shared server space to use.
Then, suddenly, it seemed as if CD drives were everywhere, and my first MacBook in 2004 had one built in.
