what about MO? (magneto-optic disks)

- WORM (write once, read many)
- WMRM (write many, read many)

and what about magnetic-tapes? (e.g. DDS4, DLT, LTO2)

which of them lasts for the most?

MO units and disks are a bit costly
say >=50 euro for 4.5Gbyte R/W cartridge
and say >=500 euro for the driver unit (SCSI)
