A device for the processing of data in the form of magnetic recordings on a rotatable recording disc by means of one or more magnetic heads which are accommodated in a head plate which during operation is spaced at a relatively small distance from the disc. The surface of the plate facing the disc is provided with two groove patterns, the geometry of which being selected so that for one specific direction of rotation the summation of the pressures in the gap between plate and disc results in an ...

A head assembly for transducing signals between a head and a recording medium includes a mechanically biased pad for pressing the medium against the head. A first fluid introduced through the head into the head/medium interface produces a first force on the medium. A second fluid introduced through the pad into the pad/medium interface produces a second, opposite force on the medium. The first force reduces the friction forces on the head while the second force maintains the medium in contiguous...

A rotating head magnetic tape recording apparatus wherein a helical wrap of magnetic recording tape is formed about a cylindrical mandrel and the headwheel. The headwheel is of a larger radius than the mandrel; thus the headwheel protrudes or penetrates beyond the adjacent mandrel surfaces. This headwheel penetration operates to (1) compensate for mandrel misalignment, if any, and (2) stress the tape in the localized track coincident with the headwheel's path. A magnetic head is mounted on the h...

Various pneumatic means are shown for lifting tape locally away from a rotating head as the rotating head moves. Only the tape in the vicinity of the head is lifted. The lifting is done with minimal pneumatic force, and done only locally about the head so that recovery time for read/write operations after a lifting operation is short, Air to lift the tape can be blown from passages around the head, from passages through the head, or from passages in front of the head. Local lifting about the hea...

A recording and/or reproducing device which utilizes a round flexible foil-type record of magnetizable material, for recording or reproducing video and/or audio signal on the foil-type record through a transducer arrangement while the record is rotated at high speed at its center and concurrently hovers above a rotation-induced air cushion. The recording and/or reproducing device is provided with a rotatable stabilization plate intermediate between the record and the stationary plate or table fo...

A rotating head magnetic tape transport wherein a helical wrap of flexible magnetic tape is formed about a stationary tubular mandrel and a rotatable headwheel which carries a slotted head of generally spherical flying contour. This rotating head includes a generally spherical surface profile to insure that the head flies with close microinch adjacency to a length of magnetic recording tape. The head's spherical profile includes two parallel airflow slots which extend in the direction of head mo...

In a helical drive tape apparatus, a rotary head drum is disposed between two sections of a split cylindrical mandrel about which a magnetic tape is guided. The head drum supports at least one magnetic transducer at its periphery, so that the total diameter of the head drum and projecting transducer is greater than the diameter of the adjacent mandrel sections. The projecting transducer has a spherical contoured portion and is configured at its leading edge, relative to the moving tape, to form ...

A multi-channel magnetic head-slider assembly having a ceramic member having a bottom slider face which is adapted to ride on a thin fluid film a predetermined distance above a moving media wherein the slider face has a hollowed out, central area having a wedge shaped inner surface formed in the interior of the bottom slider face which defines a first and second parallel planar fluid bearing support rail which extend in spaced parallel alignment along the side of the ceramic member and each of w...

A magnetic disk driving device comprising a flexible disk-shaped magnetic recording medium; a first motor for rotating the magnetic recording medium; first and second head supporting members for supporting first and second magnetic heads, respectively, the first and second head supporting members being formed with recesses from which the first and second magnetic heads project toward the magnetic recording medium; a second motor for moving the magnetic heads; and first and second arms extending ...

Opposed magnetic head sliders 22, 24 for dual sided recording on a flexible disk 26 include one or more slots 32 provided longitudinally in one of the opposed rails in order to allow the slotted rail 28 to fly and reduce flying height relative to a flexible disk 26 operating at an elevated rotational speed. The sliders additionally have a diagonally blended contour 96 for urging contaminants away from the film interface between the head sliders 22, 24 and the flexible disk 26.
