ABSTRACT:
A digital signal reproducing system includes magnetic heads attached to a rotatable cylinder. The magnetic heads have different azimuth angles. The magnetic heads serve to reproduce a digital signal having signal blocks including sync signals. A counter counting clock signals and generating at least one timing signal in accordance with the count of the clock signals. A device processes the reproduced digital signal at a timing determined by the timing signal. During high tape speed reproduction for search, the counting operation of the counter is started when the sync signal is detected and is stopped when the count of the clock signals reaches a predetermined number.
