It should be like this
# disklabel cd0
# /dev/rcd0c:
type: ATAPI
disk: MY_DISC
label:
flags:
bytes/sector: 2048
sectors/track: 100
tracks/cylinder: 1
sectors/cylinder: 100
cylinders: 2551
total sectors: 255030
rpm: 300
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # microseconds
track-to-track seek: 0 # microseconds
drivedata: 0
3 partitions:
# size offset fstype [fsize bsize cpg]
a: 255030 0 ISO9660 # Cyl 0 -
2550*
c: 255030 0 ISO9660 # Cyl 0 -
2550*
# mount /dev/cd0a /mnt/cd/

Start by putting in a disk that really should work - any factory-pressed
disk. If OpenBSD understands this, it means that the disk drive is not
completely unsupported or something stupid like that.
I presume you've already tried reading your disks on another machine.
The next step would be to read the disks on this same machine using
another OS.
Or waiting for someone with more cd9660 smarts than me to tell you why
this doesn't work - I seem to recall some recent work on supporting
multisession CDs, so the cd9660 might not be as complete as we'd like.
