ABSTRACT:
A recording or reproducing apparatus for recording or reproducing information by relatively moving a head and a sheet recording medium is disclosed. The recording or reproducing apparatus includes a stabilizing member disposed around the head and arranged to generate pressure which brings the recording medium into contact with the head in accordance with the rotation of the recording medium. The stabilizing member includes a first projection portion having a projection surface projecting toward the recording medium, a second projection portion disposed outside of the first projection portion via a groove portion formed outside the first projection portion, the second projection portion having a projection surface projecting toward the recording medium, and a cut portion formed in a portion of the second projection portion downstream from the head in a direction of rotation of the recording medium, the cut portion being formed by cutting the second projection portion from its surface which confronts the recording medium, and the depth of the groove portion with respect to the recording medium being reduced from the outer portion of the stabilizing member to the inner portion of the same.
