Abstract
Abstract A magnetic head mount assembly for accessing data tracks recorded on a magnetic medium includes a mounting post, an arm element which engages the post, and a yoke on which circuit elements are disposed. An end portion of the post is slotted to receive electrical leads for connection to the magnetic head, which is supported by an air bearing slider positioned over the slotted end portion. The arm element is preferably frustoconical to reduce mass and weight, thereby enhancing access time.
