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: An information disk store possesses an air circulation system in a substantially sealed housing, by means of which system, which includes a channel for directing air to the end of the hub on which the disks are mounted, and a low-pressure compartment that is shut off from the disk compartment by a main filter, a first positive pressure gradient from the bottom to the top of the housing is set up in the peripheral space adjacent to the disks. It is advantageous to also set up a second positive pressure gradient in the direction of rotation of the disks, in the peripheral space adjacent to the disks. The novel air circulation system can be used with advantage in all information disk storage systems in which the write and read operations may be adversely affected by dust and dirt.

Abstract: In a memory processing unit, a magnetic-head positioning device having a longitudinally actuated carriage with a guide plate carrying the head, or heads, which plate has longitudinal edges and an upper and lower face, one of these faces being in engagement with a spool wheel driving the plate via a belt and the longitudinal edges of the guide plate being guided between a pair of anti-friction bearings. Linear, three-point contact of the guide plate with the bearings and with the spool wheel is insured, regardless of lateral displacement of the guide plate, by mounting the bearings so that they are tiltable, in a plane transverse to the longitudinal movement of the guide plate, by a limited amount.
