IPC: G11B21/02
Filed: 1984-08-11
Abstract: PURPOSE:To minimize mechanical damage of a head chip due to movement of a magnetic head at start by applying sequence control so that a magnetic head movement is applied after the magnetic head reaches to some degree of turning speed when a power is applied to the titled device. CONSTITUTION:When a power key PW is operated and power is applied, a control circuit 60 energizes a signal DISK to start a DC motor 12 by a servo circuit 20 and the servo control is attained with the servo circuit 20 by using a frequency signal generated by a frequency generator 18. When a turning of the DC motor 12 reaches a prescribed speed, the controller 60 moves the head 26. As the prescribed turning speed, it is sufficient when the speed is less in a danger comparatively to give a damage to the magnetic head 26, while the magnetic head 26 is projected from the reference face and the magnetic head 26 is moved in the radial direction R of the magnetic disc 10 while being in contact with the recording face 16.
