Abstract
PURPOSE:To highly accurately position a magnetic head by mounting a magnetic head on the middle of a swing arm driven by a linear type motor at its one end. CONSTITUTION:The primary coil part 16 of a voice coil motor 15 is excited to induce the secondary coil part 23 in order to rock the respective swing arms 13, 14 in the direction of arrows A, B, thus the respective magnetic heads 24 are moved back and forth in the radial direction of a magnetic disk 2, and information is written/read in/from the disk 2. Compared with the distance l3 from a pivot part 12 which is at the center of rotation of the swing arms 13, 14 to the voice coil motor 15, the distance l4 from the pivot part 12 to the magnetic heads 24 is set shorter. Therefore, the length of move of the magnetic head in relation to that of the swing arm at its one end can be made small in accordance with the ration between the lengths of the distances l4 and l3. As a result, the accuracy of the positioning of the magnetic head can be upgraded.
