Title: Optical information recording and reproducing device
Inventor: HARADA TOSHIHISA
IPC: G11B7/09
Filed: 1987-05-22
Abstract: PURPOSE:To obtain a corrected track error signal without offset, by measuring the amplitude of a track error signal at every polarity, and subtracting a signal of 1/2 of the difference from an original track error signal. CONSTITUTION:The signals of peak holding circuits 2 and 4 are inputted to an adder amplifier 17, and since both polarity are opposite to each other, the difference, after being multiplied by 1/2, is outputted, and it becomes an output signal representing an offset quantity. The output of an adder amplifier 6 is subtracted by a differential amplifier 7, and the offset of the track error signal is corrected, which goes to zero, and the output of the differential amplifier 7 is inputted to a multiplier 10, then, it is multiplied by a signal 19, which goes to the corrected track signal 20. At this time, the signal 19 goes to the one with a value having a coefficient in which the output of a differential amplifier 5, that is the sum of the peak levels of the peak holding circuits 2 and 4 is set constant. In such a way, the corrected track error signal becomes the one whose offset is 0V and whose amplitude is constant.

Namely, the incident luminous flux which is made incident from one plane of the prism 6 is displaced by a displacement quantity (y) and projected from the other opposite plane as projection luminous flux parallel to the incident luminous flux. The angle (i) of incidence varies as the prism rotates and the displacement quantity (y) also varies; and the prism has an even number of couples of mutually opposite planes, so the projection luminous flux makes a scan reciprocally within the same range at the same speed. Consequently, the size is reduced and the scan is made with high accuracy.

Filed: 1990-05-16
Abstract: PURPOSE:To increase the processing speed by storing the operand in a first storage means and storing the number of queued operands in a second storage means at the time of the absence of the operand whose reference information matches the address information. CONSTITUTION:When a data packet generated by a program storage part is stored in an input latch 1, a hash address and a tag are generated by an address generator 2 and are supplied as the address to a queue memory through an address multiplexer to read out contents of the queue memory. Unmatch between the tag of the address and a tag from the generator 2 in a comparator 5 indicates the occurrence of hash collision. When NEXT is 0, the absence of a queue of packets having the same hash address is recognized to set the value of a free list pointer 4 and '1' to the pointer area and Next in the write flag part respectively. Thus, the overhead of sequential processing is considerably reduced to increase the processing speed.
