发明名称 Magnetic recording apparatus for positioning magnetic head to track on magnetic tape
摘要 The magnetic recording apparatus according to the present invention is arranged such that its magnetic head is discretely shifted a pluarlity of times during one revolution of its magnetic tape so that continuous recording or reproduction is performed on a spiral track when the magnetic tape is viewed broadly and it includes a detector portion for detecting a mark every revolution of the magnetic tape so that the start position of a carrier motor is adjusted by the detected signal, and thereby it is achieved to have the tracking accuracy enhanced with an economical structure. Further, the motor for the tape drive portion and the carrier motor are arranged to be independent of each other, so that the angle of rotation of the carrier motor at a time can be increased and the carrier together with the magnetic head can be shifted to a desired track position of a high speed.
