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.
A magnetic head slider having a high-pressure producing bottom surface which defines a path for passing compressed air streams produced by the rotation of a magnetic disc which flow between the magnetic head and the magnetic disc. The high pressure producing bottom surface is provided with pressure-reducing inclined grooves which separate a portion of the compressed air streams and guide them diagonally downstream to the outside.
A magnetic head comprises a slider which holds recording/writing elements at its medium opposing surface constituting a lifting force generating part and the surface area of the medium opposing surface is at most 2 mm.sup.2. A magnetic recording and reproducing apparatus has such magnetic head which is disposed on a magnetic disk having a magnetic recording layer formed on a rigid substrate while the disk is rotated at a high speed so that magnetic recording and reproducing are conducted between the magnetic head and the magnetic disk, wherein the surface roughness R.sub.max of the magnetic disk is at most 100 .ANG..
A floating head device has a floating surface for imparting a floating force for floating from a recording surface by air flow formed between the floating surface and the recording surface and a suction surface for imparting a sucking force in a relative movement of a head slider to the recording surface of a recording medium. The air inlet end of the suction surface has grooves and is disposed in down-stream of the air flow from the air inlet end of the floating surface.
A fly off transducer platform or carrier according to the invention comprises a carrier for supporting at least one read/write transducer for a data carrier and at least one skid defining a flight surface comprising a first surface which provides the said platform with its lift when it is flying above the said data carrier and a second, bevelled surface situated at the front of the flight surface with reference to the direction of movement of the data carrier in relation to the transducer carrier. The bevelled surface includes a rim at the leading edge thereof, and said rim, transversely to the said direction of movement, is greater at the front edge of the said bevelled surface than its rear such that an increased bevel surface area is provided to enhance lift.
A thin film magnetic transducer comprises a non-magnetic substrate and a pair of magnetic pole pieces having different widths. The width of the first pole piece deposited on the substrate is greater than that of the second pole piece to prevent a problem associated with misregistration between the pole pieces, which may occur during manufacture. Such misregistration generally results in a "wraparound", so that the edge of the second pole piece would have an extended portion forming an angle to the normal magnetic transitions created by the pole pieces. The width of the second pole piece is slightly less than the effective width of the data track recorded on a magnetic medium, and the data track width is relatively independent of the dimension of the first pole piece.
