Title: Optical disk reproducing device
Inventor: YAMADA JIRO
IPC: G11B7/085
Filed: 1985-11-08
Abstract: PURPOSE:To perform the retrieval of the objected position of an optical head at a high speed by converting an error time to the number of tracks accurately by using a bit of present position information as a parameter at a micro retrieving conversion device. CONSTITUTION:The bit of present position information of an optical head 8 from a signal processing device 9 is supplied, and an arithmetic unit 10 calculates the error time from a difference between the said information and a bit of objected position information. And when the error time is arrived below a prescribed value, the error time through a comparison logical unit 11 is supplied by switching a device from a macro retrieving conversion device 12 to the micro retrieving conversion device 13. At such a time, the device 13 to which the output of the device 9 is supplied multiplies the error time by a value having the bit of the present position information as the parameter and converts the error time to the number of tracks. Therefore, the number of tracks to be converted corresponding to a time error which changes corresponding to the present position from the inner periphery to the outer periphery of a disc are decided accurately and without errors because of a regulated linear acceleration, and the objected position of the optical head can be retrieved without performing an unnecessary retrieval at a high speed.

IPC: G11B20/10
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To read out a signal safely and surely under a high density record and to prevent lack of pulse in a high frequency signal part. SOLUTION: A peak pulse detection circuit 28, by taking the logical product of an output signal G of a level detection circuit 27 and an output signal RE of a zero crossing detection circuit 25, detects the pulse signal component from an analog signal RA read with a magnetic head 21 and outputs the component as a digital peak pulse signal RF. When a wrong peak pulse signal RF is generated at the time of the first reading, a slice level outputted from a slice level generation circuit 26 is reduced from a normal slice level N down to a low slice level L based on the instruction Q from CPU 29 at the time of the second reading. Consequently, the output signal G of a level detection circuit 27 does not lack in the pulses and an error-corrected peak pulse signal RF is generated.
