Abstract
A low-mass head/flexure/conductor assembly for reading and writing information with respect to a rigid magnetic recording disk. The assembly includes a read/write transducer unit, an elongate flexure, and gimbal structure interconnecting and articulating the transducer unit and the flexure for selected, limited relative roll and pitch, without relative yaw. Conductive ribbons that form part of the gimbal structure also form part of the conductive circuit provided in the assembly. The assembly has an effective mass of no more than about 1.5-milligrams. Plural, hardened, wear-resistant feet are formed on the transducer unit for enabling sliding contact with the recording surface in a disk.
Claims126
A head/flexure/conductor assembly for reading and writing information via a relatively moving recording surface of a rigid magnetic recording medium comprising
- a read/write transducer unit adapted for sliding on the recording surface during communication with the medium,
- an elongate carrier unit for supporting said transducer unit, said carrier unit having a longitudinal axis oriented substantially along a direction of said sliding, and
- gimbal structure interconnecting and articulating said units for selected, limited relative movement, said gimbal structure including a pair of laterally spaced, elongate ribbons extending between and connecting said transducer unit and said carrier unit.
A gimbaled head/flexure/conductor assembly for the reading and writing of digital information during contact with the recording surface of a rigid magnetic disk, said assembly comprising
- a slider containing a read/write head and associated head conductor structure,
- an elongate flexure structure including a flexure conductor and pivotally attached, distal to said slider, to a mounting structure, and
- a gimbal structure operatively interconnecting said slider and said flexure for accommodating limited relative movement between slider and flexure, said gimbal structure including a gimbal conductor conductively interconnecting said head conductor and said flexure conductor,
- said gimbal structure including a pair of laterally spaced, elongate ribbons extending between and connecting said slider and said flexure.
A head/flexure/conductor assembly for reading and writing information with respect to a rigid magnetic recording medium comprising
- a read/write transducer unit, wherein said transducer unit includes head structure formed with electrical coil structure which has a multi-layer, pancake-like configuration,

- gimbal structure interconnecting and articulating said units for selected, limited relative movement, wherein said gimbal structure includes a pair of laterally spaced, elongate ribbons between the units, wherein the assembly is intended for use with such a medium that has a generally planar recording surface, and wherein each layer in said pancake-like configuration is generally planar and occupies a plane substantially paralleling that of such surface.
A head/flexure/conductor assembly for reading and writing information with respect to the recording surface in a rigid magnetic recording medium comprising
- a read/write transducer unit, adapted for sliding contact with the recording surface in such a medium, the transducer unit formed with projecting sliding-contact feet for this purpose,
- a pivotally mounted, elongate carrier unit for supporting said transducer unit, and
- gimbal structure interconnecting and articulating said transducer unit and said carrier unit for selected, limited relative movement.
A read/write organization for use with a rigid magnetic recording medium that has a generally planar recording surface comprising
- a gimbaled head/flexure/conductor assembly that includes head structure formed with electrical coil structure which has a multilayer, pancake-like configuration, wherein each layer in said pancake-like configuration is generally planar and occupies a plane substantially paralleling that of such surface.
A rigid disk magnetic recording system comprising
- a rigid magnetic recording disk having a generally planar recording surface, and
- a gimbaled head/flexure/conductor assembly operable with respect to said recording surface for reading and writing magnetic information with respect thereto, said assembly including head structure formed with electrical coil structure which has a multilayer, pancake-like configuration, wherein each layer in said pancake-like configuration is generally planar and occupies a plane substantially paralleling that of said surface.
A transducer for communication with a rigid magnetic storage disk comprising
- an elongate beam extending between a mounting end and a free end, including a plurality of longitudinal electrical conductors,
- a gimbal disposed adjacent to said free end and coupled to said beam, and
- a slider connected to said gimbal having an embedded magnetic pole structure with an exposed pole tip for communication with the rigid magnetic storage disk while sliding on the disk in a direction oriented substantially along a longitudinal axis of said beam.
An information storage system comprising
- a rigid disk having a surface with an associated magnetic storage medium,
- an elongated beam extending between a pivot and a free end adjacent to said surface in a direction crossing a radius of said disk, and
- a slider connected by a gimbal to said beam adjacent to said free end, said slider containing an embedded pole structure with an exposed pole tip and in dynamic contact with said surface during communication between said pole and said medium.
