Abstract
A digital memory system of the hard or Winchester disk type, includes a series of hard disks, and pivoted mounting arms for the magnetic heads or sliders. In order to minimize the vertical, or inter-disk space occupied by the sliders and their mounting arms when used in a rotary type of head positioner, the end of a direct, or straight, mounting arm for each slider is generally ring-shaped, or of an open rectangular configuration, with the outer transverse portion of the mounting arm extending through a slot in the surface of the slider which is not intended for engagement with or proximity to the recording disk. In addition, the slider is secured to the mounting arm by a small springy resilient sheet metal member, having a broad central area with a rounded protrusion intended to engage the outer transverse portion of the ring-shaped end of the mounting arm, and being bonded to the slider at the bottom of the slot in the slider on either side of the rounded bearing member. This small springy member has two arms extending from it which are secured to the slider mount, at the outer ends of the arms away from the broader central area of the springy member, so that the slider is free t…
