Apparatus for recording flexible magnetic disks.

摘要

An apparatus for recording flexible magnetic discs contained in envelopes comprises a mandrel engageable with a central zone of the disk (14) to rotate the disk within the envelope, and a carriage (41) which is movable radially relative to the disk and on which there is mounted a pair of magnetic heads (83, 84) which oppose each other and make contact with the magnetisable surfaces of the disk. A presser pad (96), which presses the envelope containing the disk against a reference surface (97) of the apparatus, is lowered by an electromagnet (90) which also causes the upper head (84) to lower. When the electromagnet is de-energised, a spring (94) retracts the presser pad. A lever (100) biased by a spring (102) is also allowed to retract and lifts off the movable head (84) but only to an extent permitted by an adjustable stop (103).
