Abstract: MEMOIRE D'INFORMATION A DISQUES QUI COMPORTE UN SYSTEME DE VENTILATION DANS UN BOITIER RELATIVEMENT FERME QUI, PAR UNE AMENEE D'AIR CENTRALE AU MOYEN D'UN CONDUIT D'AMENEE ET PAR UNE CHAMBRE EN DEPRESSION 22 FERMEE PAR UN FILTRE 21, ETABLIT DANS LA ZONE PERIPHERIQUE 24 DES DISQUES 20 UN PREMIER GRADIENT DE PRESSION POSITIF DANS LE SENS DE LA HAUTEUR DU BOITIER. LA CREATION D'UN DEUXIEME GRADIENT DE PRESSION POSITIF DANS LE SENS DE ROTATION DES DISQUES DANS LA ZONE PERIPHERIQUE DE CEUX-CI EST EGALEMENT AVANTAGEUSE. L'INVENTION S'APPLIQUE AVANTAGEUSEMENT A TOUS LES APPAREILS DE STOCKAGE D'INFORMATION DANS LESQUELS L'ENREGISTREMENT ET LA LECTURE DE SIGNAUX SONT SENSIBLES A LA POUSSIERE ET A LA SALISSURE.

Abstract: A head positioning device for a disk drive unit comprises a Y-shaped drive band for displacing the carriage bearing the head(s), each divergent arm portion of the Y forming the same angle with the central longitudinal axis of the band. In another embodiment, the two divergent arm portions are connected together by a crosspiece. Advantageously, the drive band is made of steel having a tensile strength of from 1200 to 2500 N/mm2, especially from 2000 to 2500 N/mm2. The novel positioning device can be used with advantage in any type of system for recording, reproducing and storing audio, video, data or control signals.

Abstract: A device for positioning objects of low mass, particularly magnetic heads over preselected tracks on at least one magnetic disc in a disc file in which there is provided a carriage, displaceable toward and away from the axis of rotation of the magnetic disc, which serves as carrier not only for the magnetic heads but also for the coil of a linear drive means, the said coil being a flat coil which projects into the working air gap of a magnet assembly comprising at least one flat magnet, the flat coil and magnet assembly being arranged in such a way that the force vector lies essentially in the plane in which the carriage is displaceably mounted.

Abstract: A drive apparatus for a magnetic disc, particularly a flexible magnetic disc in an envelope, distinguished by a compact design which is achieved by so designing and arranging the linkage between the drive's closure member and disc clamping member that they take up as little room as possible. By designing the linkage in the form of a roller and lever arrangement and arranging them substantially on the central longitudinal axis of the housing of the drive apparatus in the upper portion of the housing, the maximum amount of space is available on either side of the linking means for printed circuit boards and electronic components. In a very advantageous embodiment, the closure member, linkage and clamping member and part of the housing are assembled as a single unit which is ready for fitting. The drive apparatus of the invention can be used for any kind of flexible or rigid magnetic disc.

Abstract: A positioning device for a write/read magnetic head in a magnetic disc data storage device comprising a motor-driven guide disc, with a spiral-shaped guide wall arranged at right angles to the plane of the guide disc, for a guide element in the form of a ball-bearing on a magnetic-head support. Due to the greatly reduced friction it is possible to achieve highly accurate positioning within an extremely brief period of time and with an extremely low power requirement. This device may be used to position the heads in magnetic disc systems for the recording and/or reproduction of analog or digital signals.
