Digital recording and SCMS

48
Digital recording on a Mini disc is not possible under the following conditions.
1 In case the source contains the copy prohibit code (SCMS – Serial Copy Management System).
— "SCMS ON" is displayed and the unit enters the record-pause mode.
2 Locking to the reference clock is not possible. — "UNLOCK" is displayed and Pause status is engaged.
Sampling frequency
Three types of digital signals are usually used according to the sampling frequencies. The sampling frequencies vary
depending on the types of digital equipment as shown below.
32 kHz : Standard and long-hour modes of DAT, A mode broadcasting of BS tuner, etc.
44.1 kHz : Standard mode of DAT, CD, MD, etc.
48 kHz : Standard mode of DAT, B mode broadcasting of BS tuner, etc.
(DAT : Digital Audio Tape deck)
In general, high-quality recording based on digital signal transmission is not possible unless the source and recorder
components use the same sampling frequency. As this unit has a built-in sampling rate converter, digital signals with 32 kHz
and 48 kHz can be recorded by conversion to the MD sampling frequency (44.1 kHz).
SCMS (Serial Copy Management System)
Designed for copyright protection, the SCMS is a prescription that copying of digital signals as they are in the digital form between digital audio
equipment is allowable only for one generation.
