ABSTRACT:
A rotary head apparatus of the type which reproduces digital signals recorded in one or more oblique tracks on a recording medium, the digital signals being formatted such that one frame of the digital signals is formed of n blocks, each block having added to it a block address and a frame address, wherein the apparatus compares the frame address from the reproduced signal with a reference frame address which varies with a reference period, and the transporting speed of the recording medium is then controlled so as to make the difference between the reproduced frame address and the reference frame address constant.
