[ARSCLIST] Lacquer brands

[Bob Olhsson <olh@xxxxxxxxxxxxx>]

When I started cutting in the mid 1960s, there were three brands in common use here in the U.S. They were Reeves Soundcraft, AudioDisc and Transco. From time to time people offered the Pyral disks that were imported from France. (My understanding is that they had invented the process and licensed it to Presto and Audio Devices in the U.S.)


There were four grades:

1. Master which was single sided with a single hole. These were virtually perfect with no visible bubbles on the good side. 10" was used for 7" 45s, 12" for ten inch LPs and 14" for 12" masters.

2. Double face. These had an additional drive hole for lathes not having a vacuum chuck. They were very good on both sides although with blemishes and bubbles around the edges. We used 10" and 12"

3. Single face. The same as above only some had obvious imperfections on the bad side.

4. I don't remember what they were called. Recently people call them dub plates. They were/are inexpensive and thinner disks used for promotional copies, publisher demos, etc.

Here's a link to the surviving US manufacturer:
