How much usable space is there on an 80 minute cd. Can I transfer an 6 hour vhs tape to a 80 minute cd? - cd 42 lexia

Thinking of buying a DVD recorder VHS combo. I do not know how much actual space can accommodate a 80-minute CD. Read a review where someone actually transferred 42 VHS tapes to CD. What CD are required, thank you
