Title: Optical pickup
Inventor: KATAYAMA HIROSHI
IPC: G11B7/13
Filed: 1990-03-16
Abstract: PURPOSE:To allow the exact detection of a focusing error by dividing a photodetector with a blind zone having a prescribed width as a boundary along the direction corresponding to a direction where the track image of an information recording medium extend. CONSTITUTION:The information is recorded and reproduced by using the information recording medium 8 of an optical disk 5 concentrically or spirally provided with the tracks 6 and a focus is detected by introducing the luminous flux reflected by the optical disk 5 to the photodetector 15. The photodetector 15 is formed with four photodetecting parts 15a to 15d divided along the direction X-X corresponding to the direction where the information tracks 6 of the optical disk 5 extends and the direction Y-Y orthogonal therewith. Since the dividing line of the direction X-X is the blind zone 16 of a measurably wide width l, the exceeding part of the track image is formed within the blind zone even if the image tends to exceed to the other side of the boundary in the direction corresponding to the track direction by the rotation of the track image generated by the aberration of the optical system and, therefore, the detection of the focusing error is exactly executed.

Title: Phase shift coefficient calculation system for m sequence
Inventor: NAKAMURA TAKAHARU
IPC: H04B1/69
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To execute the calculation of each tap information corresponding to each phase shift amount at high speed by performing the arithmetic operation of multiplying the vector expression of α to a present vector value and squaring the vector multiplied result or the arithmetic operation of squaring the present vector value as it is in a Galois field. SOLUTION: From a shift amount register 302 to an SW 303, the binary expression value of the phase shift amount 301 is outputted as a selection control signal 311. In the SW 303, in the case where the value of the selection control signal 311 is '0', the vector value of square operation part output 308 is latched to a latch part 305. As a result, latch output 306 becomes the same vector value as the square operation part output 308 outputted from a square operation part 307. The SW 303 selects double operation part output 310 in the case that the value of the selection control signal 311 is '1'. A double operation part 309 outputs the vector value as the double operation part output 310 by executing a 1-bit left-shift operation to the vector value of the square operation part output 308.
