An information processing, i.e. reproducing and recording, apparatus which has a rotative driving means for rotating a disk-shaped recording medium, a floating-type head for reproducing information recorded in the recording medium while floating above the disk-shaped recording medium that is being rotated by the rotative driving means, and a suspension, made of an elastic member, for supporting the floating-type head. The floating-type head has a slider which is floated by an air flow that is directed near the surface of the rotating disk-shaped recording medium. The slider has a bevelled portion at one side that faces the outer edge of the disk-shaped recording medium, such that any contact between the slider and the ridge that exists along the outer edge area of the disk-shaped recording medium is virtually eliminated. Since the slider virtually avoids contact with the ridge that exists along the outer edge area of the disk-shaped recording medium, the storage capacity of the disk-shaped recording medium can be more effectively used.
L'invention est un appareil de traitement, c'est- -à-dire de lecture et d'enregistrement, d'informations doté d'un mécanisme d'entraînement rotatif qui fait tourner un support d'enregistrement en forme de disque, d'une tête flottante qui lit l'information enregistrée sur le support d'enregistrement en forme de disque tout en flottant au-dessus de ce dernier que le mécanisme rotatif fait tourner, et d'une suspension faite d'un élément élastique qui supporte la tête flottante. Cette dernière comporte un curseur qui est maintenu en suspension par un courant d'air dirigé près de la surface du support d'enregistrement tournant en forme de disque. Le curseur est en biseau sur le côté qui fait face au bord extérieur du support d'enregistrement en forme de disque, ce qui élimine virtuellement tout contact entre le curseur et le renflement du bord extérieur du support d'enregistrement. Étant donné que le curseur n'entre virtuellement jamais en contact avec le renflement du bord extérieur du support d'enregistrement en forme de disque, l'espace de stockage du support d'enregistrement peut être utilisé plus efficacement.
