Kentaro Odaka, Takehiro Nagaki, Norikazu Horikawa · IEEE Transactions on Consumer Electronics · 1986
This paper presents the format of pre -recorded tape for playing back on a rotating-head digital-audio tape cassette recorder (DAT( ') and presents a technique for high-speed duplication of this tape. The sampling frequency of 44.lkHz is only used for pre-recorded tape and digital copying is not possible. The format also includes a wide track-pitch mode, which is used by producers of pre-recorded tape for high-speed contact duplication.
