Title: Magneto-optical recording device
Inventor: HASEGAWA MITSUHIRO
IPC: G11B5/02
Filed: 1989-03-09
Abstract: PURPOSE:To stabilize a recording condition by controlling a bias magnetic field generator arranged in the whole recording area of a recording medium so that the uniform area of a bias magnetic field can be secured with intensity necessary for the inversion of a magnetic domain in accordance with the movement of an optical head. CONSTITUTION:Printed coils 2a to 2e, 2f, 2g to 2i are arranged on the upper and lower planes of a magnetic body block 1 extended in the whole recording area with a half-pitch shift in the tracking control direction. In magnetic fields respectively generated from the groups of the printed coils 2a to 2e and 2f to 2i, the magnetic field on the overlapped position of the adjacent coils are set up to a level lower than the minimum value Hb of a bias magnetic field necessary for recording. When the optical head is moved by exciting means Q1 to Q4 into the area, the magnetic field can be lifted to a level higher than the level of the minimum value Hb by a magnetic field (a+f) by simultaneously exciting the adjacent printed coils 2a and 2f, 2f and 2b for instance. Consequently, the recording condition is stabilized.

IPC: G06F13/00
Filed: 1983-03-31
Abstract: PURPOSE:To improve the reliability by transmitting priority information transmitted from a synchronizing station for plural number of times in a loop transmission system having the synchronizing station. CONSTITUTION:The synchronizing station transmits priority information having a code representing the priority in the order of high priority. Each node checks for this priority and transmits a signal when the priority is coincident with the own priority. For example, nodes 3, 5 and 7 transmit a signal to the priority of P1 and nodes 2 and 6 transmit a signal to the priority of P2, and this procedure is repeated in the period T0. The priority information consists of a preamble PR, a start flag SF, a synchronizing signal bit SY, a priority field PI, an address DA, a sender SA, information I and an end flag EF. The field PI consists of PIA and PIB having the same content and when the relation of PIAnot equal to PIB is established because of code error or the like, the field having the higher priority is treated as the true field.

Filed: 1990-03-07
Abstract: PURPOSE:To realize stable access operation control strong against disturbance by calculating driving force in accordance with temporal change quantity of reference speed, and driving an optical head by adding it in a feedback loop. CONSTITUTION:A speed error detector 17 detects a speed error between the reference speed to change temporally and the moving speed of the optical head 2 detected on the basis of information recorded on an optical disk 1. Besides, a position error detector 10 integrates the above-mentioned speed error, and detects the position error of the head 2 to a target position. Here, computer logic 20 computes the driving force, and adds it to a loop 21 from the outside of the feedback loop 19 by an adder 21. This loop 19 is formed by summing the outputs of the detectors 10, 17 by prescribed ratio by the adder 12. Therefore, when the head 2 is driven according to the added result of the adder 21, the reference speed is switched to acceleration or deceleration, and when it changes, the necessary driving force is supplied to the head 2. Then, since the control of an error portion is executed, the stable access operation control strong against the disturbance can be realized.
