    摘要: The disk drive system (10) includes an actuator (16), responsive to an adjacent value, for adjusting the position of a data head (20) with respect to data tracks (22) located on the surface of a disk (12), and a controller (24) coupled to the data head (20) and to the actuator (16). The controller (24) receives servo information read from the surface of the disk (12) by the data head (20). In turn, the controller (24) determines an adjustment value to be applied to the actuator (16). The adjustment value is calculated dependent on a predetermined variable gain factor. Where the controller (24) determines the position of the head (20) is oscillating about the center line of a predetermined data track at a frequency above a predetermined frequency, the controller (24) reduces the gain factor applied in determining the adjustment value.

    摘要: A multimedia data storage system including a compartmentalised drawer (20) which can be tailored to accommodate the differing cooling requirements of different device types thus allowing each device type to be mounted in any device position. A cover (20) in the form of a frame having a plurality of openings (42) fits onto the front of the drawer. A first device type includes a front bezel (22) which fills one opening in the cover and is cooled by air passing through a number of holes located along the length of the lower surface of the frame. A second device type (12) is cooled by air passing through a louvred panel (46) located in one opening in the cover. The panel includes a blanking member (62) which blocks off the frame cooling holes located in front of the second device type. Thus, for this device type, there is no air flow through the cooling holes. In addition, noise coming through the holes from inside the drawer is reduced.

    摘要: An air bearing slider according to the present in­vention provides a programmable slider wherein the fly height of a the read/write head may be conveniently controlled using electrical signals. In an air bearing slider according to the present invention, the rear of the slider is made to fly lower by altering the angle of attack of a rear air bearing region. In one embodi­ment of the present invention, a slider configuration includes a first air bearing region (31) at the leading edge of the slider and a second air bearing region (32) at the slider's trailing edge. The first air bearing region includes a tapered region (37). A deformable central region (33), including a non air bearing surface, joins the first and second air bearing regions and controls the relative angle between the air bearing surfaces. The relative angle is adjusted by deforming the central region using a layer of e.g. piezoelectric material which overlays the central region. A conventional read/write head is placed on the rear portion of the second air bearing region.

    摘要: An erasable optical disk drive system is disclosed which utilizes an electron trapping media coated on the disk surface to store data in the form of light energy. Data is written onto the disk, which is contained in a light-tight contamination-free environment similar to a Winchester hard disk drive system, using a near infrared light laser beam. Data is read from the disk using a visible light laser beam. The entire optical disk drive system is designed to fit within a standard mini or 5-1/4 inch disk drive form factor for personal computers.

    摘要: Le système d'unité de disques (10) comporte un actuateur (16), sensible à une valeur adjacente, pour régler la position d'une tête de données (20) par rapport à des pistes de données (22) situées sur la surface d'un disque (12), et une unité de commande (24) couplée à la tête de données (20) et à l'actuateur (16). L'unité de commande (24) reçoit des informations d'asservissement lues sur la surface du disque (12) par la tête de données (20). En échange, l'unité de commande (24) détermine une valeur de réglage à appliquer à l'actuateur (16). Cette valeur de réglage est calculée ee fonction d'un facteur de gain variable prédéterminé. Dans le cas où l'unité de commande (24) détermine que la position de la tête (20) oscille autour de l'axe médian d'une piste de données prédéterminée à une fréquence supérieure à une fréquence prédéterminée, elle réduit le facteur de gain appliqué pour déterminer la valeur de réglage.

    摘要: Une unité de disque (20) à actuateurs multiples utilise des têtes multiples (46a-j, 47a-j) associées à des actuateurs respectifs multiples (341, 342) afin de lire des données provenant de toutes les pistes se trouvant sur la surface d'un disque, et d'inscrire des données sur ces dernières. Le positionnement de chaque tête par les actuateurs respectifs (341, 342) est régulé par des servo-informations intégrées, enregistrées dans les pistes de données. Les pistes de données ont une densité supérieure à 2000 pistes par pouce. L'utilisation de deux actuateurs (341, 342) permet des temps d'accès réduits par rapport aux temps d'accès de disques dotés d'un seul actuateur ainsi qu'une vitesse de transfert de données supérieure.

    摘要: The structure and organisation of a magnetic disk drive optimises the volumetric storage density within a device form factor by maximising the number of disks. The spindle and dual rotary actuators are supported at each end by a pair of support plates 22, 23 that are separated and supported by not only the spindle and actuator shafts, but also the voice coil motor core pieces and tie bars 52 which carry shock mounts. The head disk assembly 70 is shock mounted in the lower part 73 of a two part enclosure 72, 73 wherein the enclosure parts are aligned and separated by elastomer guides 77, 78 and the separation covered by a compliant tape 89 to complete the enclosure. Both actuators use a common servo surface while one actuator carries upwardly facing transducers and the other downwardly facing transducers so that each arm extending between disks 16 mounts only a single suspension-transducer assembly, thereby reducing the interdisk spacing. The enclosure occupies the entire vertical height of the form factor and the head-disk assembly occupies the full available height of the enclosure interior to accommodate as many disks as possible. Electrical components are excluded from the axial sides of the stack of disks.
