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 movement. A uniform, stable, hydrodynamic air film is developed over a relatively large area, generally centered on the head's transducing gap.
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 which have one end which terminates in sloped surface defining a leading edge relative to the moving media and each of which terminate in and are integral with a third flat fluid support surface forming a trailing edge which is perpendicular to said first and second fluid bearing support rails and a plurality of magnetic transducers having a preselected gap width and predetermined spacing are mounted on the end of the ceramic member at the trailing edge of the ceramic member with the gap of each head adjacent to and in alignment with said third flat support surface forming a plurality of tracks with a moving media wherein the width of each track is substantially equal to the preselected gap and the spacing between the tracks is substantially equal to the predetermined spacing between magnetic transducers is shown.

Disclosed is a novel rigid flying head supported on a prescribed foil to present a "compound-foil" face to a passing flexible record segment, the segment being thus induced to automatically assume a prescribed, relatively controlled "approach zone" and associated constant spacing relative to the head face.

A method and apparatus for removing dust from an information carrier includes a rotating member having at least one channel extending therethrough, operative to act as a centrifugal pump, and also includes apparatus for recording or playback of information from the information carrier.
A magnetic head for a rotary head drum is disclosed which can suppress abrasion thereof while a sufficient contact thereof with a magnetic tape is secured. An upper side tape sliding surface and a lower side tape sliding surface are formed on a tape sliding surface at an end of a head chip on the opposite upper and lower sides of a central tape sliding surface, which has a magnetic gap thereon, with a pair of upper and lower grooves left therebetween. The upper side tape sliding surface which is brought into contact with a magnetic tape earlier than the central tape sliding surface is formed with an increased thickness while the lower side tape sliding surface which is brought into contact with the magnetic tape later than the central tape sliding surface is formed with a decreased thickness.
