Title: Apparatus for preventing generation of vibration of disk player
Inventor: KURONUMA HIROSHI
IPC: G11B19/28
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To enable prevention of occurrence of irregular vibration even if a disk has eccentric gravity by changing the driving operation of constant linear velocity to the driving operation of constant angular velocity when the rotating velocity of a spindle motor of a disk player rises higher than the predetermined velocity. SOLUTION: When the rotating velocity of a spindle motor 1 has reached the predetermined rotating velocity, a switching transistor 18 is inverted to the conductive condition by the setting of a differential circuit 8 and an integral circuit 13, etc. When the rotating velocity of a disk is lower than the predetermined number of rotations, a transistor 18 is in the non-conductive condition and the rotating velocity control operation by the spindle motor drive circuit 5 is controlled to provide the constant rotating linear velocity by a digital signal processing circuit 4. When the number of rotation becomes higher than the predetermined number of rotations, the transistor 18 is in the conductive condition and the rotating velocity control operation is controlled to make constant the rotating angular velocity with a drive signal switching circuit 21.

Abstract: PURPOSE:To prevent a signal not relating to the off-track from being bed to the tracking control system by providing a means measuring the time storing a signal of a tracking control means. CONSTITUTION:An off-track signal generated due to the eccentricity of a recording disk 1 or of the shaft of a motor 2 is stored in a RAM 15 via a switch 11, a low pass filter 13 and an A/D converting circuit 14. Then an information processing control circuit 32 inputs a signal (line ADR) of an address counter 30, discriminates whether the value is a prescribed value or over (a value corresponding to a time of the motor 2 driven by one rotation or over), outputs a pulse signal (line MST) to a pulse generating circuit 29 again when the value is a prescribed value or below, stores the output into the RAM 15. The information processing control circuit 32 decides it as a fault of the device when the signal (line ADR) of the address counter 30 is a prescribed value or below to stop the operation of the device.

IPC: B62D1/04
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and costs, to attain compactness and a thin type, and to improve accuracy in detecting rotation by fixing a rotation detecting element to detect the rotation of a disk-shaped rotor to the center of rotation on one surface side of a circuit board facing the disk-shaped rotor so as to be surrounded with a ring-shaped contact part. SOLUTION: A circular fitting shaft part 71 to be fitted into circular bearing recessed parts 45 and 46 is formed in one face parts of driven gears 39 and 40, and a ring-shaped contact part 72 is formed in the other face parts so as to surround holding holes 47 and 48. The ring-shaped contact part 72 is brought into contact with one surface side of a circuit board 41 to surround magneto-resistive elements 57 and 58. In the magneto-resistive elements 57 and 58, their magnetic resistances are changed due to the number of magnetic fluxes that intersect the magneto-resistive elements 57 and 58.  With reference to the case that the magnetic fluxes of disk-shaped magnets 49 and 50 are directed in the direction in which the density of a magnetic flux ϕ1 that intersects the magneto-resistive elements 57 and 58 is zero, their magnetic resistances are increased according to an increase in the number of magnetic fluxes. As the magneto-resistive elements are provided at the centers of rotation of the driven gears, it is possible to detect rotation while avoiding vibrations associated with the rotation of the rotor.
