IPC: G11B19/28
Filed: 1992-06-15
Abstract: PURPOSE:To reduce the frequency of trials for switching a clock for modulating record data at a MCAV disc. CONSTITUTION:Basic clock generators 1-1 to 1-N are arranged to generate clocks for detecting sector marks and for modulating record data corresponding to respective zones and sector marl detection circuits 2-1 to 2-N to detect sector marks by sampling a reproduction signal of a disc by an output clock from the basic clock generators 1-1 to 1-N. Moreover, a pulse detector 3 is provided to send a command to a clock selector 4 so that an output clock of a basic clock generator is outputted as a clock for modulating record data corresponding to the sector mark detector which generates a sector mark detection pulse when outputs of the sector mark detectors 2-1'/2-N are inputted to let the sector mark detection pulse be inputted. This reduces the frequency of trials for sector mark detection to one thereby allowing the obtaining of the clock for modulating record data corresponding to the present zone.

Title: Noise reducing circuit
Inventor: SHIROICHI YOSHIROU
IPC: G11B20/04
Filed: 1977-12-22
Abstract: PURPOSE: To reduce the breather due to noises under the condition having no deterioration in the sound quality in a high range and no clear noise in a low range by using a preemphasis circuit having different gains for different bands.  
     CONSTITUTION: One input signal is fed to the preset LPF filter 16 of a preemphasis circuit so that the mid-range band becomes the low range signals which are attenuated more than a low range band. The other input signal is amplified by an ampli fier 17 into high range signals through an HPF 18 so that the resultant high signals are added to the low range signals from the LPF 16 by an adder 19. As a result, the composed output has a higher gain at a middle range than at a low range and has also a higher gain at a high range than the low range so that the frequency characteristics of each band is so adjusted as to have no deterioration in the sound guality in the high range. Thus,it is possible to generate such signals as have their breathers of the noises reduced under the condition having no clear noise in the low range.
