And how many of them (that are not in fact disks or intermediaries to 
disks) are suitable for acting as the physical storage for a VMware 
virtual disk? Certainly not any of the optical types. The rest are 
interconnects or mediators to some physical storage. If that storage 
isn't random access (disk), then it's not suitable as the physical 
representation of a virtual machine's virtual disk.

Magnetic tape (of the standard 9-track variety, at least) is not 
rewritable because the drive does not ensure that a new record 
precisely aligns with the one being overwritten.
