Disk-shaped magnetic recording media essentially consisting of a flexible substrate, a thin ferromagnetic metal film applied to one or both sides and a protective or antifriction layer present on this metal film and essentially consisting of carbon, a process for the production of these recording media and information stores containing these recording media.

Disk-shaped magnetic recording media, their production and information

A method and an arrangement for reducing wear in magnetic storage means having magnetic disks, in particular having flexible media, become effective when predetermined maximum waiting times of the heads on the same track or the same tracks have elapsed. The heads HD are moved away from the waiting tracks in accordance with the predetermined control scheme, may be moved in waiting areas of the magnetic surface, and are moved back to the waiting position.
