Rule on Digital Copying
The digital audio equipment exchanges audio signals in the digital forms through digital
input/output jacks, and include the CD (Compact Disc) player, MD (Mini Disc) recorder
and DAT (Digital Audio Tape) recorder. The digital audio equipment allows digital copy of
signals with little deterioration of music signals. This has made it necessary to have a copy
restriction rule for protecting the copyright, and the SCMS has been established as a result.
SCMS (Serial Copy Management
System)
With a view to protecting the copyright, the SCMS restricts the number of generations
permitted for copying of signals in the digital form between digital audio equipment to only
one generation.
Caution
• Because of this rule, the MD obtained by recording a CD on
the MD recorder cannot be copied in the digital form on
other digital equipment.
