    Abstract: A base mounting portion (60) connects the gimbal spring (40) to a load beam (36) and thereby to the actuator (22) of the disc drive which positions the gimbal (40) and slider (20) over a desired track on the disc. The gimbal (40) includes opposed flexure arms (62, 64) which are formed of elongated members, each having a proximal end and a distal end which define an opening therebetween. The proximal ends of the flexure arms (62, 64) are operably coupled to the base (60), and the distal ends are cantilevered. A mounting tab (66) is positioned between the ends of the flexure arms (62, 64) and supports the slider (20). Bridge sections (76, 78) are provided which connect the distal ends (74) of the flexure arms (62, 64) to the mounting tab (66), the bridge sections (76, 78) extending at an angle relative to the flexure arms (62, 64) and being angled back toward the base section (60) of the gimbal (40).

    Abstract: An optical disc data storage system includes an optical disc (54) for storing information in an optically readable format on a data surface. A slider (70) is positioned proximate the data surface of the optical disc (54). An actuator (72) coupled to the slider selectively positions the slider (70) relative to the data surface. An optical waveguide (50) having a radially graded index of refraction extends between a first end (76) positioned proximate a light source (78) and a second end (52) coupled to the slider (70) and positioned proximate the data surface. The optical waveguide (50) carries light (80) therebetween.

    Abstract: A gimbal spring (38) for supporting a slider (20) relative to a disc (12) surface. The gimbal spring (38) includes opposed flexure arms (48, 50) extending from a base of the gimbal spring (38). the flexure arms (48, 50) are designed to support the slider (20) coupled to the gimbal spring (38) via a mounting tab (54) to pitch and roll relative to the disc (12) surface. The flexure arms (48, 50) are formed of elongated members extending from the base to define a fixed end and an extended end. The flexure arms (48, 50) include an intermediate portion between the fixed end and the extended end having a reduced mass, which is less than the fixed end and extended end. The reduced mass enhances the operation characteristics of the gimbal spring (38).

    Abstract: A flying head mechanism includes a flying head, a suspension and an actuator which applies a load force through the suspension. The load force applied by the actuator is adjustable while the head is in operation. The actuator may actively control load force as part of a feedback loop which maintains the flying head at a constant flying height. One embodiment disclosed includes a voice coil actuator. In embodiments using an optical flying head, a conventional focus sensor may provide a signal indicative of flying height, since the focus signal inherently indicates flying height error.
