Title: Method and device for controlling voice control motor in hard disk drive
Inventor: DAVID P MAGGIE
IPC: G11B5/55
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To improve the method for controlling a voice control motor by allowing a non-zero speed at the time after the prescribed 2nd period to have the amount capable of traveling a device to the 2nd position and also stopping there without receiving a control signal. SOLUTION: The actuation system consisting of a voice coil motor, a voltage driver and a reading/writing head arm is simulated to the 3rd system by a 3rd transfer function so that the control signal suitable for moving the reading/ writing head from the 1st position to the 2nd position in the shorter time than the time in the case simulated to the 2nd system is easily applied. In the hard disk control system, the reading/writing head is made to move to the 1st intermediate position by the voice coil motor in the 1st period, and the reading/writing head is moved to the 2nd intermediate position in the 2nd period, then in the 3rd period, the voice coil motor is entered to the inactivated mode while traveling the reading/writing head to the final position.

Title: Optical disk
Inventor: UENO FUMIAKI
IPC: G11B7/24018
Filed: 1987-10-23
Abstract: PURPOSE:To continuously execute reproduction, recording, or erasing on the both sides of an optical disk by recording, on the recording surfaces on the both sides, information spirally so that the spiral sequences of recorded information are inverse to each other. CONSTITUTION:On the surface of an optical disk 1, information is recorded spirally 2-1 clockwise from inner to outer, but on the rear surface, information is recorded spirally 2-2 counterclockwise from outer to inner. In the surface end part, a surface end signal is recorded as well as a surface end preliminary signal in a position preceding the end-signal position by a length equivalent to several seconds, and the information is reproduced by a front side head from inner to outer. If the surface end preliminary signal is detected, a rear side head operates, upon the detection of a surface end signal, reproduced signals and transfer servo tracking signals are switched to those from a rear side optical head, and thus the reproduction is executed continuously from the front surface then from the rear surface.

Abstract: PURPOSE:To keep a constant output voltage and a constant band width in spite of the change of input current by decreasing the potential of the gate electrode of an FET when a peak rectifier output is increased corresponding to that the input currents are increased and the output voltage is increased. CONSTITUTION:The intensity of an input light is changed, and the current of a photodiode 4 is increased from an anode direction to a cathode direction.
