Title: Method for jumping track and multi-beam optical head
Inventor: FUJITA TERUO
IPC: G11B21/08
Filed: 1994-03-08
Abstract: PURPOSE:To jump a track without leaving the track without being scanned, by continuing reading of a precedent data track and reading a data track which is different from the precedent data track and not yet scanned. CONSTITUTION:A condensed spot 8 scans an (n+1)th data track 7 and a condensed spot 9 scans an (n+2)th data track. The spot 8 is then let to jump to an (n-42)th track. A jump pulse from a jump pulse generator circuit 32 is input to a drive circuit 30 through an adder 28. As a result, the drive circuit 30 drives a galvano mirror 18 in a T1 direction, so that the spot 8 is let to jump to the (n+2)th track. When tone jumping is finished, the generator circuit 32 stops operating, and the spot 8 scans the (n+2)th track. During this time, the condensed spot 9 performs a general tracking control. Therefore, data tracks are never left unscanned because of jumping of tracks.

Title: Phase control circuit
Inventor: FUJIMURA HIROSHI
IPC: H04L7/02
Filed: 1979-03-31
Abstract: PURPOSE:To make it possible to maintain a fixed phase relation between write and read clocks by controlling an inhibiting circuit for read clocks by exercising a supervision over whether clocks are supplied to write and read counters. CONSTITUTION:Once input data and the 1st and 2nd clocks are applied to terminals 11, 12 and 13, write and read counters 19 and 20 start operating. When a phase difference between write clock WD and read clock RD exceeds a fixed value, inhibiting pulse generating circuit 30 supplies inhibiting pulse IH to FF31 and gates 37 and 32 inhibits the 2nd clock from passing through. While the 1st and 2nd clocks are supplied, clock OFF detecting circuits 33 and 34 send their outputs to eliminate the output of gate 36. The output of gate 36 is delayed 38 as long as the phase difference between clocks WD and RD reaches the fixed value and led to gate 37. Therefore, when clocks WD and RD bears the fixed phase relation, the phase control of circuit 30 is never performed unitl either the 1st or 2nd clock is interrupted.
