IPC: G11B21/10
Filed: 1987-04-24
Abstract: PURPOSE:To always highly accurately control a head even when the amount of the decentering of a disk is larger by preliminarily storing the deviation of head position due to decentering, and controlling the head. CONSTITUTION:A sensor 6 to detect the position of the head 2 is provided. At the time of starting the operation, the head 2 scans on a rotary disk 1, and signals from the sensor 6 are written in a memory 8 corresponding to a track position signal obtained by a track address generation circuit 9 and the rotary phase signal of the disk 1 supplied from a phase address generation circuit 13. Then, at the time of accessing a track, a signal read out from the memory 8 and a signal from the sensor 6 are compared with each other by a comparator circuit 16, and thus the position of the head 2 is servo-controlled 17. As a result, a highly accurate control can be executed at all time even when the amount of decentering of the disk is large.

Title: Optical pickup device
Inventor: MURAO ARITAKE
IPC: G11B7/1369
Filed: 1988-04-25
Abstract: PURPOSE:To obtain a small-sized high-resolution optical pickup device by providing a light source which emits a laser beam, reflected light detector, optical modulation element, and feedback circuit. CONSTITUTION:A laser beam from a laser diode 1 irradates a disk through a lens 2, half prism 4, lambda/4 plate 4, object lens 5, electrooptical element 6, and acoustooptical element 7. The reflected light are condensed to a photodetector 10 by means of a lens 9 after they are reflected by the half prism 3. When a focusing error occurs, a correction circuit 11 calculates the correcting amount of the signal of the photodetector 10 and a drive circuit 13 corrects the focusing position by adjusting the voltage applied across the electrooptical element 6. In case of a tracking error, a correction circuit 12 calculates the correcting amount of the output of the photodetector 10 and a drive circuit 14 adjusts the supersonic frequency added to the acoustooptical element 7. Thus the tracking shift of the incident light to the disk is corrected. When the shift exceeds the correcting limit of the correction circuit 12, a drive circuit 15 adjusts the focusing position by moving the whole device by driving a motor 16. Thus the need of mechanical control of the object lens 5 is eliminated and the device can be miniaturized.

Abstract: PURPOSE:To provide a positive active material with which an organic electrolyte lithium battery of a superior long-term preservation performance can be obtained by either crushing iron pyrite or purifying iron pyrite before it is crushed, then washing the crushed iron pyrite with water. CONSTITUTION:In pulverized powder of iron pyrite which has a particle diameter of below 50mum and is washed with distilled water or demineralized water, almost no sulfur dioxide exists even after long-term preservation. Accordingly, in an organic electrolyte lithium battery constituted using the thus treated iron pyrite powder as a positive active material, its voltage characteristic and internal resistance characteristic do not deteriorate almost entirely even after long- term preservation at high temperature thereby exhibiting almost the same characteristic as the initial one. Thus, an iron disulfide-lithium battery having superior characteristics can be obtained.

Abstract: PURPOSE:To miniaturize a recording/reproducing device of magnetic disk and to prevent injuries of a disk by providing a stabilizing plate which stabilizes the head abutting state by press-contacting with the disk, and a mechanism which abuts/separates the head and the stabilizing plate to and from the disk. CONSTITUTION:The upper and lower support arms 18 and 19 fixed with a magnetic head 17 as well as a stabilizing plate 16 which holds a jacket 3 vertically are supported by shifts 21 and 22 at the bases of both arms. While the tip sides of both arms 18 and 19 hold a cam 10 having a square section. When a disk 4 is driven, the head 17 rubs stably the disk 4 by the function of the plate 16. Then the cam 10 is turned by 45 deg. when the record/reproduction proceeds to the next track. Thus the plate 16 and the head 17 are separated from the disk 4. In such a case, a carriage 2 moves horizontally by an extent equivalent to a track. Thus the cam 10 is turned more by 45 deg. to perform the record/reproduction of the next track. Therefore the contact/separation between the disk 4 and the head 17 and the feed of the head 17 are carried out by the same drive source. In such a way, a recording reproducing device is miniaturized with no injury to be inflicted to the disk 4.
