For a short while, there were disks and drives available that had both optical and magnetic storage. The optical part, if I recall, was WORM (Write Once Read Many), like current CD-R technology. The magnetic part was just like floppy drive technology. The idea was basically that you could store some data "permanently" and unalterably on the disk, while maintaining the flexibility of also having storage on the disk that could be altered at will. I may be incorrect in some particulars, I'm going by memory from many years ago. As I recall, those drives were never very popular because while they attempted to combine the best of both worlds they really ended up combining the worst of both worlds, and the drives and disks were expensive to boot. As far as "disc" v. "disk", the correct spelling is disk. Technically there is no word "disc", it isn't a part of the English language. Spelling it with a c instead of a k was basically just a way of setting computer "discs" apart from other disks. The original question about "optical disks" v. CD technology, I have no idea what is being referred to as "optical disks". Optical disks are CD and DVD as far as I know.
