Infos zu Shamrock und Ampex Bändern

[bitbrain2101]

Hallo,

ich habe gerade im Netz ein interessantes Dokument mit Infos zu Shamrock und Ampex Bändern gefunden. Hier ein Auszug


Shamrock / Emerald Low Cost / Off-Spec Stock
 011—1.5 mil low cost / rejected NB acetate tape (sold as Shamrock or Emerald) (1960s)
 021-- 1 mil low cost / rejected NB acetate tape (sold as Shamrock or Emerald ) (1960s)
 031-- 1.5 mil low cost / rejected polyester tape (Was available in 2500' pancakes as well as 7"
reels in 1983) – 1960s to 1980s (sold as Shamrock or Emerald )
 041-- 1 mil version in 7" only - low cost / rejected polyester tape – 1960s to 1980s
o Note: The 041 was used as the code for Shamrock worldwide, and the formulations sold
under this number changed over time. The same code was found on the tabs for
Concertape sold by Radio Shack in the 1980s.
 051-- 0.5 mil low cost / rejected polyester tape – 1960s to 1980s

Rejected steht für abgelehnt/ zurückgewiesen, NB steht für non backcoated.
