ABSTRACT:
An apparatus is provided for loading a head onto a spinning disk and unloading the head from the spinning disk so that contact between the head and the disk is essentially prevented. The apparatus includes a Whitney-size head joined to the flexure of a Whitney-type suspension arm. A triangular-shaped ramp is fixed to a face of the suspension arm for engagement with a stationary cam. The stationary cam is located along the path of movement of the head, suspension arm and flexure. The contact between the cam and ramp causes movement of the head relative to the disk. In the case of loading the head, this movement results in a desired approach of the head towards the disk and enhances loading of the head onto the disk.
