Abstract: PROBLEM TO BE SOLVED: To utilize only the existing constitution as open driving in the position other than near the inversion position, to improve the throughput of scanning and moreover to prevent the overrun in the stopping position by executing speed servo control when reaching near the inversion position in the case of transferring a head to the inversion position. SOLUTION: When starting scanning in the direction L with a movable head 1, a position control loop is cut with a main controller 7, and the maximum level of accelerating coil driving voltage in the open loop is applied to a linear motor 13 via a driver 12. The movable head 1 is accelerated in the direction L at the maximum acceleration. When the speed of the movable head 1 approaches the prescribed scanning speed, control is switched into a constant speed servo control, and recording and reproducing in the information track are executed with the movable head 1. When finishing recording and reproducing, the accelerating coil driving voltage in the direction R is applied to the linear motor 13 in the open loop.

IPC: H01F7/18
Filed: 1980-08-05
Abstract: PURPOSE:To suppress the generation of noises and vibrations as well as to achieve longer life of components and prevent from drift of their setting points by slowing rise-up and falling-down of a magnet drive current. CONSTITUTION:With input of a magnet drive signal DV, a voltage at point A increases up to the level determined by a voltage division ratio of resistors R2 and R3. Thereby, a reference voltage of comparator 16 increases gradually according to the time constant R1.C1. At the same time, the output of comparator 16 activates a magnet drive circuit 15, so a current I is supplied from the driving voltage source VD to a magnet coil L. A voltge at point B increases and is supplied to the comparator 16 to compare with a reference voltage, so the current I flowing through magnet coil L increases gradually. After an object to be activated has been operated, a holding signal HD is inputted. With disappearance of magnet drive signal DV and holding signal HD, the current flowing through magnet coil L decreases gradually.
