ABSTRACT:
An actuating device for lifting and lowering a magnetic-head assembly of a drive mechanism of a magnetic-disk storage apparatus includes a landing lever associated with a laterally projecting cross-arm supported by a supporting plate which extends parallel to the landing lever. Via a guide lever pivotally mounted to a housing of the apparatus, the supporting plate is moved towards the diskette by a connecting rod against a spring force as soon as the front cover is closed.
