ABSTRACT:
A device for the recording and/or reproduction of data with use of a flexible magnetic disk, or a floppy disk, having information bearing surfaces on both sides. A pair of transducer heads are disposed on both sides of the rotatably supported disk for movement substantially in its radial direction in data transducing contact with its opposite surfaces. One of the heads is gimbal mounted on a carriage slidably mounted on guide rails whereas the other head is gimbal mounted on a carrier arm which is spring mounted on, and biased toward, the carriage. A vibration control system is mounted on the carrier arm in order to minimize its audible resonant vibration due to the data transducing contact of the transducer heads with the magnetic disk. Typically the vibration control system comprises a metal-made, inverted-U-shaped shielding plate mounted on the carrier arm via bodies of rubber or the like in overlying relation to the transducer head carried by the carrier arm.
