摘要： The invention relates to a structure for and a method of adjusting the position of a magnetic head especially tangentially of a magnetic disk with improved accuracy for use in an optomagnetic disk device. The device has a head support unit 20 comprising a pickup 12 having an objective lens 10 mounted thereon, and a head arm 14 connected to the pickup 12 and provided with a magnetic head 16, the head arm 14 being adjustable in position relative to the pickup 12 so that the magnetic head 16 is opposed to the objective lens 10 on the pickup 12, the head support unit 20 being movable radially of the disk. The pickup 12 has at least one screw hole 22 for attaching the head arm 14 thereto, and the head arm 14 has a slit 24 opposed to the screw hole 22 of the pickup 12 and in parallel to the tangential direction of the disk. A screw 26 is slidably fitted in the slit 24 of the head arm 14 and has its distal end screwed in the screw hole 22. An elastic member 30 is provided between the screw 26 and the head arm 14 for pressing the head arm 14 against the pickup 12.

摘要： To accurately move a pickup 31 along a radial line of an optical disc in an optical disc apparatus for recording signals on both sides of the disc or reproducing the signals from the both sides, the pickup 31 is mounted on a support base 30 coupled to transport means and movable by being guided by a U-shaped guide assembly 5 which is fixedly and accurately positioned on a chassis carrying a disc drive motor. The guide assembly 5 comprises a pair of straight travel guide portions disposed in parallel to each other on opposite sides of the plane of rotation of the disc, and a circular-arc guide portion interconnecting the two guide portions. When reproducing the recorded signals, the pickup 31 accurately reciprocatingly moves on the disc radial line along the straight travel guide portions, and when the reproduction position is changed from one side of the disc to the other side, the pickup quickly moves upward or downward along the circular-arc guide portion.
