Device and method for recording information on a magnetic data storage medium
11250883 · 2022-02-15 · ·

Disclosed is a device for recording information on a magnetic data storage medium which comprises a magnetic field source designed to be capable of generating a magnetic field in the region where the magnetic data storage medium is arranged; a source of electromagnetic radiation at a matrix of controllable mirrors; and a matrix of controllable mirrors mounted in a housing so as to be capable of reflecting electromagnetic radiation by means of the controllable mirrors into the region where the magnetic data storage medium is arranged and/or in another direction. The present invention makes it possible to record information on a fixed magnetic data storage medium.
