[78-L] OT: Re: Playing reels backwards -PS

[Kristjan Saag]

Talking about tapes: there's an ongoing discussion on a record 
collectors' website about how to interpret the mx digits and letters on 
(US) Columbia LP's.
There seems to be a general agreement that the first digit in the final 
part of the mx number indicates which studio tape is being used for 
cuttings. Also that the next mark, a letter or a combination of letters 
ranging from A-L, indicates the number of the cut from which stampers 
were made.
What confuses me is the number of the tape. When magnetic tape was used 
for serving the cutting lathe, did the studios use first and second and 
third generation tapes? There seems to be evidence that Columbia 
actually multiplied the series of "first cuttings" by using three 
different cutting lathes to produce three first mothers. So the 1A, 1B 
and 1C Columbias are all first cuttings.
But what about the tape? Magnetic tape doesn't wear out like stampers 
do, so at what point did Columbia change tape for further cuttings?
Anyone has a clue?
