The starting track field specifies the starting track number for which the
TOC data will be returned.
The data is returned in contiguous ascending
order.
Valid values for the starting track field are lh to 63h.
A value of
AAh requests that the starting address of the lead out area be returned.
The TOC data returned is a four byte header followed by one or more (up to
100) TOC track descriptors.
The last track descriptor is for the lead-out
area.
The format of the CD Address is determined by the LBAMSF bit in the
CD-ROM parameters page.
See Section 5.3.1.4.

contents data.
The value of TOC data length does not include itself.

of contents.
IMPLEMENTORS NOTE:
A disc may start at any track number.
