Abstract
A rotary to linear converter is disclosed as adapted for use as a transducer positioning mechanism in a magnetic disk drive wherein a transducer is transported across a series of concentric data storage tracks on a disklike record medium for accessing the individual tracks. A band of flexible, nonstretchable material such as stainless steel is looped about a pulley on a bidirectional drive motor shaft, with the opposite end portions of the band extending tangentially away from the pulley. The opposite ends of the band are anchored to a carriage, carrying the transducer, at points spaced from each other in the direction in which the carriage is to be moved reciprocably upon bidirectional rotation of the drive motor. While one end of the band may be coupled directly to the carriage, the other end is coupled thereto via a generally U-shaped spring member which is biased for imparting tension to the band at the time of assemblage. The band is medially secured to the pulley as by a threaded fastener element extending through a clearance hole in the band.
