Abstract

PURPOSE: To attain stable reproduction after pickup movement by holding a constant relation between a pickup method and carriage at any time when the lock group of a signal reproducing device which scans a recording track by turning a disk is generated.
CONSTITUTION: Carriage 1 is moved at a constant speed in the radius direction of disk 10 according to the groove pitch of disk 10 and pickup method 5 consisting of a cantilever has reproducing stylus 6 supported atop. In the constitution, when a locked group is generated, pushing member 9 of an actuator driving part is put into pulse motion by the signal of detecting method 11 to push cantilever 5 once by a constant distance and motor 4, on the other hand, is turned faster than normal rotation for a certain time to shift carriage 1 more by (d). Consequently the relation between the pickup method and carriage is held constant.
