Abstract

PURPOSE: To effect the track location of high quality by consecutively comparing the track numbers read out and the track numbers designated from their upper units so as to control the location moving speed of a scanner.
CONSTITUTION: The address signals detected by a pickup 3 and corresponding to a track number are stored in a memory 6 and then transferred to a memory 7 so that they are compared by a comparator 8 with the subsequent address signals which are to be stored in the memory 6. If both of the signals are identical at their upper units, a gate 9 is opened by the compared output of the comparator 8. Then, the upper units of the address signals stored in the memory 6 are compared by a comparator 10 with the upper unit of the address signals of the designated track which is designated by a key board 11 and stored in a memory 12 so that the scanning operation of the pickup 3 is controlled at a high speed through a control circuit 13. Likewise, the lower units of the address signals of the reading track and the preset address signals are compared so that the pickup is gradually controlled to a lower speed to effectively use the reading address signals, thus making it possible to effect the track location having less error and high quality.
