ABSTRACT:
A recording and reproducing apparatus having a rotary head drum includes a timing signal converter for converting one of a first timing signal and a second timing signal to the other. The converter comprises a generator for generating first and second select signals, a memory for storing the first timing signal in response to the first select signal and for reading out the stored signal in response to the second select signal, a processor for processing the output signal of the memory to generate the second timing signal synchronously with the rotation of the rotary head drum, and a recording/reproducing head for recording the second timing signal onto a slant track formed on a recording medium, and for reproducing the second timing signal. The reproduced second timing signal is processed and supplied to the memory for storage therein in response to a signal synchronous with the rotation of the rotary head drum and for subsequent read out therefrom in response to a signal unsynchronized with the rotation of the drum so as to generate a timing signal indicating the position of the recording medium.
