Abstract
A magnetic recording apparatus includes an arm, an airvane, a regulating member, and an urging member. The arm has a head slider including a magnetic head at a free end thereof, and is moved by an actuator device between a scan position and a stop position. The arm scans a surface of a disk for reading and/or writing information thereon at the scan position. The head slider is elastically supported on the arm by a flexure. The airvane is disposed adjacent to the disk, and is urged to a first position in opposition to a direction of air flow generated by rotation of the disk. The airvane moves in response to air flow generated by rotation of the disk to a second position in the direction of the air flow. The regulating member is provided at a position corresponding to the stop position of the arm and connected with the airvane. The regulating member moves between a regulating position for regulating vertical movement of the flexure by contacting the flexure and a non-regulating position for moving away from the flexure. The urging member urges the airvane to the first position so that the flexure is regulated by the regulating member when the disk is not rotating.
