Abstract: A mechanism for supporting a record/regeneration head of a magnetic disk unit and optical disk unit that includes a minute-displacement actuator is designed to protect an electromagnetic device or optical device from electrostatic damage while maintaining the performance of the actuator. The mechanism for supporting a record/regeneration head comprises a slider (2) with an electromagnetic device or an optical module, and a suspension (3). The slider (2) is held by the suspension (3) by means of the actuator (4) that serves to displace the actuator. The suspension (3) has a grounding area that is connected electrically with the slider (2) through an electrical connector (8) capable of moving and/or deforming in the direction in which the slider (2) is displaced by the actuator (4).

Abstract: Examples of a load beam are described herein that include a lifter tab extending towards a distal end, a dustpan defined by a dustpan forming line at a proximal end and the lifter tab at a distal end and a first and second plurality of rail sections separated by a longitudinal axis. The first and second plurality rail sections including a rear rail, an intermediate rail, and a front rail. The rear rail extends from a proximal end of the load beam to the first intermediate rail, the intermediate rail extends from the first rear rail to the dustpan forming line, and the front rail extends from the dustpan forming line to a proximal end of the lifter tab.

Abstract: A drum assembly for a helical scan recorder comprises a stationary first drum and a shaft having a shaft first end centrally mounted to the first drum and a shaft second end. The drum assembly further comprises a rotatable second drum which has at least one transducing element mounted thereon. The shaft extends axially through the second drum and the shaft second end protrudes axially above the second drum. The drum assembly also comprises a physical support member connected to the first drum. The physical support member is connected to the first drum and also connected to stabilize the shaft second end while allowing rotation of the second drum. The physical support member is connected to the shaft second end to reduce deflection of the shaft second end when the drum assembly is exposed to external vibration or shock.

Abstract: A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information representative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also includes an arm which has a first layer of material including a plurality of elongated fibers orientated in a first direction, and a second layer of material including a plurality of elongated fibers orientated in a second direction. The first and second layers are part of a composite material. The transducer is attached to said arm. The resulting actuator arm has a resonant frequency that can be varied or moved or shifted by varying the direction of the elongated fibers in the second layer with respect to the direction of the elongated fibers in the first layer. The resonant frequency is varied so that it is at a different frequency than the resonant frequency peaks associated with the other components of the disk drive, such as the resonance frequency of the disk or disks of the drive and the head suspension assembly (HSA). The arm may also include signal-carrying wires which are positioned between the layers of the composite arm and heat conductive fibers to remove heat from a heat producing source, such as from a chip on the arm.
