Title: Tracking error detector
Inventor: HIRABAYASHI MASAYUKI
IPC: G11B7/09
Filed: 1988-04-22
Abstract: PURPOSE:To always detect a stable tracking error signal by detecting the maximum value of plural values obtained by extracting reproducing signal amplitude values from the clock timing positions of a prescribed bit and bits before and behind that. CONSTITUTION:Registers 7-9 fetch and store the amplitude values detected respectively in the timing position where a bit 50 is originally detected and the timing positions before and behind that. A comparative selector 11 compares the values stored in the registers 7-9 with each other, selects their maximum value and outputs a value into which the reproducing amplitude value of the bit 50 is digitally converted. In the same way, a digital value corresponding to the amplitude value of a bit 51 is obtained by registers 12-14 and a comparator selector 15. A controller 19 inputs the reproducing signal of a clock bit 52, generates a timing signal with this as a reference, supplies it to the registers and controls them. A subtracter 20 calculates the difference between the reproducing signal amplitude values of the bits 50 and 51, that is, the tracking error signal. A D/A converter 21 converts an obtained digital signal into an analog signal and outputs it from an output terminal out.

Abstract: PURPOSE:To activate without fail even at the time of generating drop-out by controlling the output signal of a synchronizing signal separating circuit with the output signal of a level comparator. CONSTITUTION:Since a drop-out detecting circuit 15 has a threshold voltage, a level detector 17 outputs a drop-out pulse which is shown in Fig.(e).

Here, at the time of an electric power rising, the drop-out detecting circuit 15 considers it as the long drop-out. At this time, since a differentiating circuit 16, a reference voltage source 18 and a level comparator 17 control the long drop-out pulse with a prescribed length, a clamp pulse is surely generated and a clamp action comes to be secure.
