READ/WRITE HEAD RETRACT MECHANISM |
摘要 |
A retract mechanism for a magnetic head which can read from and/or write to a disk, the mechanism includes a spring arm which supports the head and urges the head toward the disk. The spring arm includes a cam follower which rides along the surface of the cam, which has two parallel horizontal surfaces and two incline surfaces. The spring arm is moved by an actuator in a radial direction along the disk. When the spring arm is moved radially away from the center of the disk, the cam urges the spring arm upwardly, thereby lifting the head up and away from the disk. As the spring arm continues to move radially away from the center of the disk, the cam guides the spring arm such that the head rests safely on a landing platform.
