  • Patent number: 4672490
    Abstract: In a recording and reproducing device for a magnetic disc, a swingable holder fixedly supports a first magnetic head, while a carriage supporting the holder swingably further supports a second magnetic head in a fixed manner. During a head-load time, the first and second magnetic heads are held in contact with the upper and lower surfaces of the magnetic disc at positions opposite to each other thereby to record or reproduce information to or from the magnetic disc. The recording and reproducing device of the above described construction is further improved by providing a damper device in a moving range of the holder so that the damper device can reduce impact when the first and second magnetic heads are brought into contact with the magnetic disc.
