ABSTRACT:
With a device for pressing at least one magnetic read/write head (16) against a recording medium (14) in motion relative to it with a swivel-mounted pressure lever (52) carrying the read/write head (16) that runs in the recording medium's (14) direction of motion and is pressed to the recording medium (14) by means of spring force and with stationary guide elements (76, 78) that limit read/write head (16) movement at right angles to the recording medium's (14) direction of motion. The read/write head (16) is equipped with pivot pins (90, 92) that, in the pressed operating position of read/write head (16), define a swivel axis lying approximately parallel to recording medium (14) as well as its direction of motion and that are held in the position at pressure lever (52) as well as by means of guide elements (76, 78) that are displaceably directed in the direction of pressure of the read/write head.
