摘要： A multiple actuator disk drive (20) utilizes multiple heads (46a-j, 47a-j) associated with respective ones of multiple actuators (341, 342) to read data from and write data to all tracks on the surface of a disk. The positioning of each head by the respective actuators (341, 342) is controlled by embedded servo-information recorded in the data tracks. The data tracks have a density of greater than 2000 tracks per inch. Utilizing two actuators (341, 342) provides access times which are reduced with respect to the access times provided by disk drives having a single actuator and an increased data transfer rate.

摘要： A 3 1/2-inch form factor disk drive architecture. The architecture includes storage disks (26), for storing data and transducers (60) for reading information from and writing information on the storage disks. An actuator assembly (50), responsive to control signals, is provided for selectively positioning the tranducers with respect to the storage disks. A circuit board (15) generates control signals to control the actuator assembly and for providing information signals to and receiving information signals from the transducers. The architecture also includes a housing defining the maximum height, length, and width of said disk drive, the housing having a maximum height of approximately one and 65/100ths inches (1.65"), the housing including: a base (12) having a top, a bottom, a first end, a second end, a first side and a second side, the base for supporting the storage disks about a first support post (31), the base supporting the actuator assembly about a second support post (40); a cover (14) secured to the first and second support posts and sealably attached to the top of the base to enclose the storage disks, the transducers, and the actuator assembly; and a shock frame (25), having a first and second sides mounted adjacent said first and second sides of the base, the shock frame secured to the cover.

摘要： A disk drive (10) having dimensions of 5.15 inches long, 4.00 inches wide, and 0.805 inch high is provided. The disk drive (10) includes a cover (14) engaging a base (12) to form therebetween a controlled environment isolated from ambient atmosphere conditions. A storage medium, comprising a single magnetic plated disk (22) having a central point (21) to a plurality of concentric tracks, is rotatably mounted on said base (12) within the controlled environment. A means (20) for rotating the storage means about an axis passing through its center point, preferably comprising a spindle motor (20), is also mounted on said base (12). Transducers (60), one per disk surface, for reading and writing information to the disk (22), are mounted on an actuator (50) which positions the transducers (60) over selected, individual, concentric tracks on the disk (22). A printed circuit board (PCB) (15) provides control signals to the spindle motor (20), transducers (60), and the actuator (50) to selectively access the stored data.

摘要： A latch mechanism (146) for locking an actuator arm (160) in a disk drive (36) includes a latch (184) pivotably supported in the disk drive for engaging the actuator arm and an electromagnet (183) for capturing and holding the latch to disengage the latch from the actuator arm. A spring (188) is provided to bias the latch to engage with the actuator arm. A swivel plate (194) is provided on the latch mechanism and the electromagnet captures the swivel plate; in particular, the electromagnet has two poles, (190a and 190b) and the swivel plate contacts one of the poles and an air gap exists between the swivel plate and the other pole. The air gap allows the electromagnet to release the swivel plate. The swivelling action of the swivel plate causes the swivel plate to seat with the entire surface of the one pole of the electromagnet, increasing the ability of the electromagnet to hold the swivel plate once the swivel plate has been captured.
