Abstract: A disk drive (30) conforms to the 1.8 inch form factor through use of, for example, a removable cartridge (200) which has a disk (220) mounted on the hub (226) which hub (226) is manipulatable by a multifunction handle (58) of the disk drive (30), allowing the hub (226) to be seated on the spindle motor nose (56) of the disk drive (30). The multifunction handle (58) of the drive (30) provides for a compact, high capacity design by performing cartridge hub seating operations, cartridge ejection operations, head arm assembly unlocking operations, and handle locking and unlocking operations to ensure proper operation of the disk drive (30). The disk drive (30) includes an inventive ramp (66) design which allows the head arm assembly (64) to be initially received within the cartridge (200) as the cartridge (200) is inserted into its final registration position in the disk drive receiving mechanism (53) and to be more tangent with respect to the disk (220).

Abstract: Une cartouche (20) destinée à une unité de disques (130) comprend un volet (44) qui peut être poussé d'une position fermée vers une position ouverte dans laquelle le volet se trouve pratiquement à l'intérieur de la cartouche (20) et dans un plan sensiblement parallèle au disque (42) contenu dans la cartouche (20). Celle-ci comprend un mécanisme de montage (48) permettant de déplacer le volet (44) de la position fermée à la position ouverte, et un mécanisme de verrouillage (50) servant à verrouiller le volet (44) dans sa position fermée. En outre, la cartouche (20) comprend une rainure (52) qui s'étend vers l'arrière à travers la cartouche afin de verrouiller la cartouche à l'intérieur de l'unité de disques (130).

Abstract: A headerless, faul-tolerant sample-data servo pattern, comprising an alternating sequence of first and second servo sectors (300, 300'), with the first servo sectors each including a partial track address and circumferential orientation information (330), and the second servo sectors each including a full track address (335 and 340), provides an absolute indication of a read/write head's circumferential orientation along a given track on a magnetic disk which is robust in the presence of defects in the magnetic recording medium.

Abstract: A removable cartridge disk drive (100) includes a removable cartridge (20) adapted to be received by a disk drive (100) having a base plate (104) and right (102) and left (103) guide walls. The cartridge (20) inserts into the drive (100) at an angle by means of a movable slider (116) attached to one of the guide walls (102). Once inserted, the cartridge (20) is locked in and held. During operation, a rotary actuator arm (180) with adjustable angular orientation loads one or more read/write heads (182) off of a fixed ramp (176) onto the surface of a data storage disk (42) contained inside the cartridge (20). After read/write operations are finished, the head (182) is unloaded onto the fixed ramp (176) and the cartridge (20) is ejected from the drive (100) at an angle.

Abstract: Une unité de disque (100) peut recevoir une cartouche (20) ayant un disque (42) d'un diamètre de 3,5 pouces environ qui peut contenir au moins 150 mégabytes de données, comprenant un mécanisme de fonctionnement (112) pour amorcer et réguler le positionnement d'un bras actuateur (176) sur lequel est monté un transducteur de lecture/écriture (178), la position d'un moteur à broche (224) qui est utilisé pour mettre en rotation le disque (42) contenu dans la cartouche (20) jusqu'à ce qu'il atteigne sa vitesse de fonctionnement, le verrouillage de la cartouche (20) dans l'unité de disque (100) dans un mode de fonctionnement et l'éjection de la cartouche (20) de l'unité de disque (100). Le mécanisme d'actionnement (112) peut fonctionner afin d'éjecter la cartouche (20) même si l'unité de disque (100) n'est pas alimentée en puissance électrique, afin de retirer la cartouche (20) et la transporter vers une autre unité de disque (100) ou vers un endroit sûr.
