Abstract

PURPOSE: To execute stably high speed reproduction of odd times by forming helically a track on a magnetic tape by using a rotary head, and using tracking information used for an automatic tracking (ATF) system.
CONSTITUTION: A motor 5 is rotated at a constant speed by converting an output of a frequency generator varied in accordance with a revolving speed of its motor 5, to a voltage by an F-V converter 8, and applying it to a driving circuit 10, and also brought to rotation control so that an output of a tracking detecting circuit 11 is applied to a driving circuit 10 through an adder 9, and heads 1a, 1b execute an on-track to a track recorded on a magnetic tape 12. A speed control loop of the motor 5 works so that an input signal frequency of the F-V converter 8 becomes constant, therefore, when a frequency division of a frequency dividing circuit 7 is 1/N, a rotating speed of the motor 5 becomes N times as high as the regular reproducing time. Even in this case, an output of the tracking detecting circuit 11 is applied to the driving circuit 10 through the adder 9, and the track recorded on the magnetic tape 12 and the heads 1a, 1b are brought to on-track control, as well.
