Magnetic Disks
Audio Disks: Magnetic disks have been used to store digital data since the 1950s. In the 1960s, Ampex introduced the CueMat to attempt to displace the NAB Broadcast Cartridge tape. It was not well received. Someone we know may be willing to help transfer one of these. Note for Minidiscs, see the magneto-optical/minidisc page.
Data Disks: There are a wide variety of data disk formats which are beyond the scope of our services. We can read some Zip-100 and Jaz discs. As a courtesy, here are a few recovery services with good reputations: Ontrack, Multinational — DriveSavers, Northern California — CBL, Multinational — Critical Data Recovery, Toronto. We haven’t had the need to use any of these due to the extensive backup protocols in place. We have two separate 1,000 GB storage units in different buildings that are synced overnight. This is discussed here.
