Abstract
A rotary head cylinder of a rotary head assembly includes a first projection for reducing jitter. The first projection is smoothly formed in the vicinity of a point where a tape is separated from a fixed cylinder and is extended in a lengthwise direction of the tape. A second projection is provided for increasing a restricting force on an upper edge of the tape in a direction toward a surface of the fixed cylinder. The second projection is smoothly formed in the vicinity of a lower edge of the tape at the same point on the fixed cylinder and is extended in the lengthwise direction of the tape.
