ABSTRACT:
A magnetic reproducing device such as a VTR, DAT, or the like reproduces recorded information from inclined tracks on a magnetic tape, having auxiliary information, such as address information, recorded in areas in the inclined tracks, includes a rotary magnetic head rotatable for successively scanning the tracks on the magnetic tape to generate a reproduced signal representative of the auxiliary information. A pulse signal is generated having pulses in synchronism with each rotation of the rotary magnetic head through a predetermined angle. Window pulses used subsequently to extract the auxiliary information in the areas from the reproduced signal are generated based on the pulse signal.
