Abstract

PURPOSE:To easily change a head and to obtain a stable floating characteristic by providing a pneumatic piping having an inlet port in the vicinity of the rear surface of the head attaching surface of a gimbal to which the floating type magnetic head is attached, along a head arm. CONSTITUTION:The inlet port 8 for air opened in the vicinity of the rear surface of the head attaching surface of the gimbal 2 is disposed at the front end of the pneumatic piping 5 disposed along the head arm 4. At the time of a rotation start and stop on which a recording medium 3 does not reach a fixed rotation, when the air is charged from the pneumatic piping 5 interlockingly with a rotation command signal and a stop signal, the gimbal 2 is sucked to the inlet port 8 and a head core 1 is separated from the recording medium 3. Consequently, on loading and unloading the head, there are no parts to be connected to the head, the head can be easily changed and during the floating of the head, there is no other influence, so that the stable floating characteristic can be obtained.
