摘要： PROBLEM TO BE SOLVED: To enable high-speed and smooth movement by eliminating fluctuation in an engaging state between a rack and a pinion for driving a recording head. SOLUTION: The head drive having a rack 6 disposed in a recording head 1 slid with respect to a recording disk and a pinion 11 engaged with the rack 6 and rotated by a driving motor 10 is provided with a recessed groove 8 disposed in the rack 6 and extended in parallel with rack teeth 6A, and the rotary shaft part 17 of the pinion 11 disposed in a swing arm 14 integrally having the guide 18 of a rigid body guided by the recessed groove 8 and swung. When the rack 6 is inclined in a moving direction, the swing arm 14 is swung along the inclination of the rack 6 to maintain constant a space between the rack 6 and the pinion 11. Since the swing arm 14 is a rigid body, it is not necessary to abut one of the rack and the pinion on the other by using a spring force, and no extra force is applied on a gear tooth surface between the rack and the pinion.

摘要： PROBLEM TO BE SOLVED: To provide a guide shaft inclination adjusting method capable of highly accurately adjusting parallelism between a plane on which the recording medium of a turntable is loaded and a plane vertical to the optical axis of a recording medium device. SOLUTION: In a first adjusting step, the two PN1, PN2 of the three mounting surfaces of a skew angle adjusting fixture J1 are mounted on both end sides on a first guide shaft 32a, and the remaining one mounting surface PN13 is mounted on one end side on a second guide shaft 32b. In this state, by an automatic collimator, parallel lights are respectively made incident on a plane mirror RB and an optical plane OF1 rotated by a turntable. A reflected light from the plane mirror and a reflected light from the optical plane are returned to the automatic collimator, and the height of the other end is adjusted by using the height of one end of the first guide shaft as a reference so that the reflected light from the plan mirror and the reflected light from the optical plane are parallel to each other.

摘要： PURPOSE:To improve driving characteristics, to simplify a driving control circuit and to improve the stability of control by practically equalizing the weight of two movable parts including needles connected to respective coupling members. CONSTITUTION:The weight of a balance weight 51 fixed to a connecting member 8 is set so that the weight of one united movable part consisting of two needles 2, the connecting member 8, a photocoupler 50 and a weight 51 is equal to that of the other united movable part consisting of two needles 4, a connecting member 9, a reflector 38, and its fixing means. Since the two movable parts have practically equal weight, the same driving force will be applied to coils 22, 24 in tracking control (i.e., the control of movement of two movable parts in the same direction on the X1-X2 direction). Consequently, the output of a control circuit part 62 can be inputted to two driving control parts 64, 65 as it is and the constitution of the circuits can be comparatively simplified.
摘要翻译：目的：提高驱动特性，简化驱动控制电路，并通过实际上均衡两个可移动部件的重量来提高控制的稳定性，这些可移动部件包括连接到各个连接部件的针头。构成：固定在连接部件8上的平衡锤51的重量被设定为使得由两个针2，连接部件8，光电耦合器50和重物51组成的一个联合的可移动部分的重量等于由两根针4，连接部件9，反射板38及其固定装置构成的其他联合可动部。由于两个可移动部件具有相同的重量，因此在跟踪控制（即，在X1-X2方向上沿相同方向的两个可移动部件的移动控制）中将施加相同的驱动力到线圈22,24。因此，可以将控制电路部分62的输出原样输入到两个驱动控制部分64,65，并且可以比较简化电路的结构。

摘要： PURPOSE:To reduce the number of parts greatly by using a feed screw which engages a half nut incorporated in an optical head and moves the optical head by its rotation even as a base for the optical head in common. CONSTITUTION:A hole 6 is formed in a main chassis 1 so that a pickup device body 5 which records and reproduces information on and from an optical disk 2 is movable in the radial direction of the optical disk 2. A guide shaft 7 which supports the pickup device 5 slidably in the disk radial direction is provided to one side of the upper part of the hole 6, and the pickup device body 5 is supported slidably at the other side and the feed screw 9 is provided. The half nut 10 engages the feed screw 9 in the pickup device body 5 while the engagement is reinforced through the operation of a leaf spring 11, and an abutting guide 12 is fixed at the side of the pickup device body 5 and contacts the outer peripheral surface of the feed screw 9. This abutting guide 12 is made of a plastic material and also functions as an abutting guide for the guide shaft 7. Consequently, the number of parts is decreased greatly and the cost is reduced.

摘要： PURPOSE:To improve tracking capacity, disturbance resistivity, workability for assembling, etc. by regulating the moving direction of an optical pickup to the tracking direction by using a pin as a fulcrum by a rocking means in the following-up operation of a driving mechanism. CONSTITUTION:Guide rails 20 and 30 are set in parallel with a tracking direction A, and the first carriage 10 is guided by guide rails 20 and 30 and is freely moved. An optical pickup 40 is constituted as one body together with a movable coil 15 of a linear motor, and a linear motor yoke 16 is set in parallel with guide rails 20 and 30. In case that the first carriage 10 is stopped and held in a desired position, an electromagnet 70 is turned on. Then, a plate 71 is bent by the magnetic attraction and is brought closely into contact with the electromagnet 70. Thus, the carriage 10 is held fixedly to the plate 71 as an immobile member. In case that the following-up operation to match a minute spot from the optical pickup 40 to a track on an optical disc is performed, the movable coil 15 is moved by a minute extent after the first carriage 10 is stopped and held in a desired position by a positioning means.

摘要： PURPOSE:To improve reliability of an optical disk device by providing a loading/ unloading means for bringing an optical head close to an optical disk or separating it from said disk, so that the optical head and the optical disk do not contact with each other at the time of a positioning operation of the optical head. CONSTITUTION:When an optical disk 2 is installed and starts to rotate in the direction as indicated with an arrow B, a positioning device 6 starts a positioning operation, but in this case, an optical head 4 is at a position (interval epsilon) separated from the optical disk 2. When the optical head 4 reaches a prescribed position 4' and stands still, the optical head 4 is moved in the direction as indicated with an arrow C1, and at an adjacent position (interval delta) to the disk 2, a focus adjusting operation and a track follow-up controlling operation are executed, and when write or read of an information at this position is completed, the optical head 4 is separated from the optical disk 2, and moved onto the following designated track in a state of the interval epsilon, and thereafter, keeps the interval delta by a loading operation again, and the focusing operation and the track follow-up operation are executed.

摘要： PURPOSE:To perform tracking with high precision regardless of the movement precision of a carriage by performing tracking operation independently of the carriage. CONSTITUTION:A linear motion holding mechanism 22 is not in operation during seeking operation, so a facing yoke 23 is not attracted by a flat plate type electromagnet 21. The carriage 10, therefore, moves freely. The holding mechanism 22 operates after the seeking operation and the electromagnet 21 attracts the facing yoke 23 to hold the carriage 10. An oscillatory motion holding mechanism 20 stops its operation at this point of time. An optical pickup unit 15 is therefore allowed to oscillates through a bearing 16. Namely,the follow-up control to a track is carried out. The correction width of eccentricity from the track is about 300mum, so the angle of rotation around the bearing part is extremely small, and the influence of variation in a rotational direction is hardly exerted.
摘要翻译：目的：通过独立于滑架执行跟踪操作，无论滑架的移动精度如何，都可以高精度执行跟踪。构成：在寻求作业期间，直线运动保持机构22不工作，所以面对的轭23不被平板型电磁铁21吸引。因此，托架10自由移动。保持机构22在寻求操作之后操作，并且电磁体21吸引相对的轭23以保持托架10.振荡运动保持机构20在该时间点停止其操作。因此，允许光学拾取单元15通过轴承16振荡。即，执行对轨道的后续控制。轨道的偏心校正宽度约为300μm，因此轴承部件周围的旋转角度极小，旋转方向的变化影响很小。
