Filed: 1987-03-13
Abstract: PURPOSE:To shorten an operating time by controlling the irradiating position of a light beam to a target track position, by operating a tracking control circuit according to the second tracking error signal, based on the target track position, when the irradiating position of the light reaches the target position through a track jump. CONSTITUTION:The displacement of the irradiating position of the light beam from the target track position is detected by a second error signal generating means M8 as an error signal to show the shift of the irradiating position of the light for the target position. Then, the said error signal is inputted to a tracking control means M4 by the operation of the error signal switching means M9 until the irradiating position of the light comes to the target position. Accordingly, after the completion of a tracking jump, the tracking control means 4 is temporarily due to control the irradiating position of the light to the target track position, and the irradiating position of the light is rapidly controlled to the target position by the tracking control means M4. Thus, the irradiating position of the light beam can be rapidly controlled to the target position only by executing once a track jump control.

Title: Mask signal detection circuit
Inventor: OTAKE HISAO
IPC: H04L27/14
Filed: 1989-03-14
Abstract: PURPOSE:To reduce the area of the circuit occupied in a semiconductor chip by storing discrimination of a time between code change points of an input signal subject to amplitude limit for plural number of times and discriminating whether or not the pattern of the signal is coincident with a pattern appearing when the signal is an MSK modulation signal. CONSTITUTION:When an MSK modulation signal with a space frequency fSS is inputted to an input terminal 1, the time between code change points is tA and then the MSK modulation signal with a mark frequency fM is inputted, the time is tC and the crossover point of the both is a time tB. Thus, the time between code change points of an output signal 12 of a limiter circuit 3 is a time window TA, TB or TC without fail. The output signal 12 of the limiter circuit 3 is inputted to a time discrimination storage circuit 4 between the code change points and a delay detection circuit 9. A discrimination circuit 5 applies discrimination based on the output of the code change point from the time discrimination storage circuit 4. Thus, only when the MSK modulation signal is inputted to the input terminal 1, the discrimination circuit 7 outputs the detection signal.
