cdrom: "df" != real size ?

hi,

when I type df I see:

venus:~# df
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/hda2 985329 493077 441348 53% /
/dev/scd0 94 94 0 100% /cdrom

this does mean that there are 94x1024x1024 bytes = 94MB on CD?
or is this wrong ? I guess so, because when I tar the whole thing,
I'll see:

venus:~# tar -cf cdrom.tar /cdrom/
venus:~# ls -l cdrom.tar
-rw-r--r-- 1 root root 297768960 May 29 07:40 cdrom.tar

but this would mean that 1 block on cdrom is 3093.510638 bytes each.
hmm ... where is the error?
