ABSTRACT:
A rotary drum includes a plurality of reproducing heads each having a plus azimuth angle (+azimuth angle), which heads are collectively arranged at a location in the circumferential direction of the rotary drum in such a manner as to be in close proximity to each other, to be taken as a +azimuth reproducing head group, and a plurality of reproducing heads each having a minus azimuth angle (−azimuth angle), which heads are collectively arranged at a location in the circumferential direction of the rotary drum in such a manner as to be in close proximity to each other, to be taken as a −azimuth reproducing head group, wherein the +azimuth reproducing head group and the −azimuth reproducing head group are spaced from each other in the circumferential direction of the rotary drum. With this rotary drum, signals can be certainly reproduced from recording tracks with narrowed widths by using the multiple reproducing heads arranged on the rotary drum.
