Abstract: PURPOSE:To improve the resolution while simplifying the configuration by emitting an infrared ray from an LED lamp when a position of an optical unit is detected so as to detect the position of each light spot with a reflected light from a reflecting plate whose angle is sequentially changed attended with the movement of the unit. CONSTITUTION:When an optical unit 20 starting movement from a reference stop position P0 moves a position P1 to other position P2, a reflected light 21b1 by an optical reflecting plate 22 of a radiated infrared ray 21a at the position P1 is made incident in a lens 19 at a reflecting angle beta1 and a light spot is produced at the position P1 on the surface of a position detection element 23 via the lens 19. In this case, a current i1-1 from the point P0 of the element 23 and a current i2-1 larger than the current i1-1 from the point P1 are outputted respectively and the currents are inputted to a CPU 15 through a current - voltage conversion circuit 24 and an amplifier circuit 25, as prescribed voltages V1, V2. Thus, the position and other information are subjected to arithmetic operation processing by the CPU 15.

Title: Annular disk clamp, its production and disk drive system
Inventor: ANBURISH MISURA
IPC: G11B17/038
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide the annular disk clamp for fixing a disk stack to a spindle motor. SOLUTION: This annular disk clamp 400 is called a shrinkage fitting clamp, and is required to be heated to expand before inserting this clamp into a hub 33 of the spindle motor. After the insertion into the hub of the spindle motor, an external load 415 in the axial direction is given to the disk clamp. When the disk clamp is cooled while the external load is given, the clamp is shrunk to provide the hub of the spindle motor with grip force. Subsequently, the external load is removed. The annular disk clamp has an upper surface 403, a lower surface to be in contact with the disk stack and an inner circumferential surface 413 to be in contact with the hub. The inner circumferential surface is brought into contact with an outer diameter (outer side cylindrical surface) 414 of the hub in an optimised area 406 to be in contact with the hub to provide the grip force locally on the hub.

Abstract: PURPOSE:To lessen an influence upon a pressing force due to a fixing error by supporting a supporting device on two guide spindles which support and guide the supporting device through a rolling member, as the rolling member, supported by a leaf spring shaped elastic body, being brought into contact with the guide spindle. CONSTITUTION:An optical head 2 is supported by first, second and third rolling parts 5, 6, 7 and is moved by these members 6, 6, 7, as being guided by the first and the second guide spindles 3, 4, and gives such operations as recording, reproducing and erasing to a recording medium 1. Besides, the optical head 2 is provided as well with the fourth and the fifth rolling members 8, 9 and the sixth and the seventh rolling members 10, 11 to support and guide the guide spindles 3, 4 from below. Then, these rolling members 10, 11 are constructed so as to guide the optical head 2, as being in contact with the guide spindle 4 through the elastic body 12 of leaf spring shape, and the fixing error or the like is absorbed by the deflection due to the elasticity of the leaf spring 12. By making the spring constant of the leaf spring 12 against the displacement of the rolling members 10, 11 sufficiently small, the adequate pressing force can be given to the respective rolling members 5-11.
