  • Transducer head assembly
    Patent number: 4647998
    Abstract: A magnetic recording/reproducing unit comprises a magnetic head for recording or reproducing information on or from a magnetic recording medium, a pushing member provided opposite the magnetic head via the magnetic recording medium for pushing the magnetic recording medium to the magnetic head, a housing for accommodating the magnetic head, and an elastic member arranged between the magnetic head and the housing for elastically supporting the magnetic head. Even if the pushing member collides with the magnetic head via the magnetic recording medium in the recording or reproducing mode, the shock of the collision is absorbed and a spacing loss between the magnetic head and the magnetic recording medium is suppressed.
