I did one of my engineering reports on this.
Also the vinyl was not reflective enough. This made the reading harder as
well as the tracking. (probably would freaky out, off of those bad +8
pressings)
There was also a DIGITAL record, with on/off bits cut into the vinyl
(read with a regular stylus). I believe that problem with this was that
they couldn't fit enough bits on the record and it could only record about
10-15 minutes.
Then someone combined the two ideas, scraped the vinyl, and made the CD
player.
