Abstract
The head slider has a substrate with a transducer on an outflow end of the substrate and rail planes, facing a disk, formed along sides and a front of the substrate. In addition, projections extend from the rail planes toward the disk. Two projections are near the outflow end of the substrate while one projection is near the inflow end of the substrate.
Claims9
A head slider for a magnetic recording drive, comprising:
- a substrate having an air inflow end and an air outflow end and defining a main plane facing a magnetic disk, said substrate holding a transducer at said air outflow end, information being read or written from/in said magnetic disk by said transducer;
- a front rail formed on said main plane near said air inflow end, said front rail defining a front rail plane facing said magnetic disk;
- first and second side rails defining first and second side rail planes, said first and second side rail planes facing said magnetic disk, said first and second side rails arranged on said substrate for receiving a floating force caused by rotation of said magnetic disk;
- a first projection arranged on said front rail and extending from said front rail plane, said first projection placed near said air inflow end of said substrate;
- a second projection arranged on said second side rail and extending from said second side rail plane, said second projection placed nearer said air outflow end of said substrate than said first projection;
- and
- a third projection arranged on said first side rail and extending from said first rail plane, said third projection placed nearer said air outflow end of said substrate than said first projection;
- whereby a loading force from said head slider upon said magnetic disk when said head slider is in contact with said magnetic disk is divided solely among said first projection, said second projection and said third projection.
