Abstract

Figs. 1, 2 and 3 show a small motor and gear box 1 which is mounted on the rotary assembly and drives an eccentric cam 2 to impart linear movement to the slide bar assembly 3. The slide bar assembly 3 moves along the outer edge and the slot in arm 7. At the end of the slide bar assembly, nearest the transducer head, is attached a flat metal spring 5 which when the slide bar assembly is extended, moves down and (Image Omitted) pushes the head and suspension assembly 6 away from the disk's surface. When the slide bar assembly 3 is retracted, the spring rides back up the suspension and rests on the mounting plate of the suspension, which is supported by the arm, allowing the head and suspension assembly 6 to float freely on the disk's surface.

pushes the head and suspension assembly 6 away from the disk's surface. When the slide bar assembly 3 is retracted, the spring rides back up the suspension and rests on the mounting plate of the suspension, which is supported by the arm, allowing the head and suspension assembly 6 to float freely on the disk's surface. Another feature of the structure assures head and suspension alignment and allows ease of assembly by using a flat spring to hold the head in position while an alignment dowel 8 ensures proper head alignment every time the head is loaded and unloaded from the disk. The suspension mounting plate is nested in the arm 7 and is held in place by a flat spring 4. This ensures accurate position while allowing ease of assembly. The alignment dowel 8 is engaged each time the head is unloaded. This assures proper angular alignment once the suspension is initially set.
