Abstract

PURPOSE:To enable a high speed and good retrieving by converting the relative speed of an information carrier and an information converting means to the frequency and performing a track retrieving by correcting a discrete value of a pulse of a track intersecting detection means. CONSTITUTION:In the case of transferring relatively the information carrier 2 and the information converting means 1 by a transferring means 10, the number of the track intersection is counted by the pulse obtained from the track intersecting detection means 12. Furthermore, the pulse from the track intersecting means 12 and the the pulse from a frequency converting means 20 are counted by an up-down counting means 22 and the arithmetic operation of said both counting results is performed by an addition and subtraction means 24, the transferring means 10 is stopped by the results of the arithmetic operation. By this method, the high speed and good track retrieving are performed without being influenced by the dropout on the information carrier 2 and dust, etc.
