Magnetic transducer platforms with protective fairing

Claim 2

Apparatus for supporting a magnetic transducer adjacent to a data surface of a movable data carrier, the apparatus comprising a magnetic transducer supporting structure including a principal member having a surface containing the magnetic transducer, and a suspension device having one end connected to the principal member and another end connected to means for carrying the structure so as to dispose the surface of the principal member opposite the data surface of the data carrier; and means for modifying the flow of air around the principal member and the suspension device comprising a substantially U-shaped framework enveloping substantially three sides of both the principal member and the suspension device, all three sides being remote from the data surface, whereby the resultant air turbulence on the magnetic transducer and its supporting structure is minimized.

Claim 3

Apparatus according to claim 1 wherein the transducer is operative to read and/or write data on the data surface of the data carrier when the principal member has an air bearing spacing between its surface and the data surface of a moving data carrier.

Claim 4

Apparatus according to claim 1 wherein said first data carrier is a transducer supporting magnetic disc, said structure and said magnetic disc together constituting a disc memory.

Claim 5

Apparatus according to claim 1 wherein said U-shaped framework comprises a plurality of walls perpendicular to said data surface and a protective wall parallel to the data surface, said walls shielding said principal member and said suspension device from turbulent air flow.

Claim 6

Apparatus according to claim 1 wherein said surface of said principal member includes a plurality of skids and a groove.

Claim 7

Apparatus according to claim 1 further including another magnetic transducer supporting structure being disposed on an opposite side of said U-shaped framework from said first-mentioned magnetic transducer supporting structure and comprising: another principal member having another surface containing another magnetic transducer, and another suspension device connected to the other principal member and to another means for carrying the other magnetic transducer supporting structure so as to dispose said other surface opposite another data surface of another data carrier that is spaced from said first-mentioned data carrier; and wherein another substantially U-shaped framework is formed on said first-mentioned U-shaped framework to envelop substantially three sides of said other principal member and said other suspension device, all three of such sides being remote from said other data surface, whereby the resultant air turbulence on said other magnetic transducer and its supporting structure is minimized.

Claim 8

Apparatus according to claim 6, wherein said data surfaces are disposed on first and second magnetic discs, respectively, with the data surfaces being parallel and facing each other with said supporting structures located between the data surfaces, and said U-shaped frameworks shield said principal members and said suspension devices by blocking air flow parallel to said data surfaces.

Claim 9

Apparatus according to claim 7 wherein said U-shaped frameworks include walls disposed on opposite sides of said supporting structures and extending perpendicular to said data surfaces.

Claim 10

Apparatus according to claim 8 wherein said U-shaped frameworks include a common wall joining said walls on opposite sides so as to separate said principal members and said suspension devices of the respective supporting structures.

Claim 11

Apparatus as set forth in claim 9 wherein said common wall extends the length of said suspension members.

Claim 12

Apparatus as set forth in claim 9 wherein said walls on three sides extend above and below a plane of the common wall so as to form a protecting enclosure on each side of the common wall for each suspension device and associated principal member.
