the 'pre' in the TOC listing isn't referring to pregap. It's referring
to 'preemphasis'.

 n the very early days of CDs (early 80s), this was a hack to allow
studios to directly press CD from masters that had originally been
made for vinyl records, which use a preemphasis curve.  These days,
nearly all old recordings have been remastered for CD and new masters
are made without preemphasis.  I haven't seen a CD with preemphasis in
over 20 years.

As for pre-gap, it's up to the CDROM whether reading the pregap is
supported at all.  Many cdrom drives are unable to access it.  If the
CDROM is pregap capable and the disc has a pregap, it can be ripped as
'track 0'.
