Restrictions On Digital Copying - Sony MDS-B5 Operation Manual

4-6 Restrictions on Digital Copying

Track mode data recorded to a disc during
recording
Track mode data consist of eight bits of information
recorded in the user TOC (Table Of Contents) area on
the disc indicating such disc-related conditions as
copyright status, digital copy restrictions, disc use, and
emphasis data.
Two track mode bits, d2 and d3, which indicate
copyright status and restrictions on digital copies, are
explained below.
Track mode
d1 d2 d3 d4 d5
d2: Copyright status 0: Copyrighted
1: Uncopyrighted
d3: Digital copy generation 0: Original
1: First-generation copy or later
When recording an input signal from the
ANALOG IN or AES/EBU connector or an
IEC958-TYPE1 digital input signal
(for professional use)
The disc will be completely copy-enabled by the Serial
Copy Management System. This status is indicated by
the track mode bit values of d2=1 and d3=1.
When recording an IEC958-TYPE2 digital input
signal (for consumer use)
Three types of discs can be produced, depending on
the sub-code information included in the input signal.

An MD which contains analog signals recorded on a
consumer MD recorder can used to make a first-
generation digital copy. No restrictions are placed on
digital copying of MD recordings made on
professional MD recorders, as long as the recording is
made on an MDS-B5. When copying analog signals,
you can use the LevelSync (track marking) function to
record track numbers automatically.
See "7-2 LevelSync Setting (Track Marking Function)" on
page 7-2.
The conditions for digital copying, as determined by
track mode bits d2 and d3, are shown below.
