Pioneer SCSI-2 - Manual (Page 128)

Read TOC
- 115 -
IMPLEMENTORS NOTE:
The first track number is not required to be one. A disc may start at any valid track
number. The track numbers between the first track number and the last track number are
required to be in contiguous ascending order, except for the lead-out track.
The ADR field gives the type of information encoded in the Q sub-channel of the block where
this TOC entry was found. The control field indicates the attributes of the track.
The track number field indicates the track number for which the data in the TOC track descriptor
is valid. A track number of 0AAh indicates the track descriptor is for the start of the lead-out
area.
The absolute CD-ROM address contains the address of the first block with user information for
that track number as read from the table of contents. An MSF bit of zero indicates that the
absolute CD-ROM address field contains a logical block address. An MSF bit of one indicates
the absolute CD-ROM address field contains an MSF address.
IMPLEMENTORS NOTE:
The starting logical block address value recovered from the TOC has a tolerance of zero for
data tracks and plus or minus 75 CD sectors for audio tracks. This tolerance is multiplied
by a factor dependent of the logical block length.
