Abstract
A rotary head apparatus for recording and/or reproducing an information track to/from a magnetic tape having predetermined orientation characteristics is constructed by: a first magnetic head having a first azimuth angle; a second magnetic head which has a second azimuth angle whose performance is relatively inferior to that of the first magnetic head and forms or reproduces the information track of a width larger than that of the first magnetic head; and a rotating member for rotating the first and second magnetic heads. The angle of the second azimuth angle for the orientation direction of the tape is larger than that of the first azimuth angle.
