An LP old an early (1980) digital recording. This one does not have that "early CD Digititis" and since it's recording predates CDs by several years I would think it was not recoded using the 44.1/16 digital standard. Sounds like it was done at a higher bitrate, but unfortunately other than stating that it is a PCM digital recording there are not technical details anywhere on the cover or in the liner notes. Decent sound (I can't give a definitive evaluation since right now my mancave has been turned into a temporary Boy Scout warehouse, holding all of the troop gear for next weeks trek to summer camp. So much for room acoustics!), but it doesn't sound bad in an early CD kind of way.
Most early digital recordings were less than CD's 16 bit resolution. One of the most popular early formats was
Sony PCM-F1, which allowed saving the data to a betamax video cassette tape. The early units were 14 bit. Glenn Gould's 1981 Goldberg was recorded on this, in 14 bit audio. But it actually sounded really good, and the old machines are are still prized and used on classical recordings today. I used F1 on 3 projects that went to vinyl. We used a prototype 16 bit Sony machine recorded to broadcast TV videotape in 1985. They needed the superior TV tape machine to eliminate wasting the last 2 bits on error correction needed with the smaller betamax tapes. Digital storage was not on the horizon. The original betamax tapes don't last though...
So in 1980, your record was probably 14/44.1. But good vinyl mastering with tubes could fix the digititis if there was any.
Sample rate is much more important than bit depth. 44.1 was the standard for a long time before higher sample rates appeared in the 90s with the DVD standard.
I hope you get your tunes back soon.
