Abstract

A suspension arm for an optical transducer comprises a load beam, a slider coupled to the load beam by a gimbal assembly and including an optical transducer positioned adjacent to an end of the slider facing a pivot point of the suspension arm, and an optical fiber for transmitting light toward the transducer, wherein an end of the optical fiber is positioned adjacent to the transducer such that light emitted from the fiber passes directly to the transducer. Disc drives that include the suspension arm, and a method of transmitting light to an optical transducer, are also included.
