US 2006/0221504 A1 · Head suspension

Abstract

A head suspension for a hard disk drive is thin from an arm to a head and involves a minimum step between the arm and a load beam. The head suspension includes a load beam that includes a rigid part and a resilient part. The load beam applies load onto a head that is arranged at a front end of the load beam to write and read data to and from a disk arranged in the hard disk drive. The head is connected to read/write wiring patterns of a flexure. The flexure supports the head and is attached to a disk-facing surface of the rigid part. An arm is attached to a carriage of the hard disk drive and is turned around a spindle. The arm supports the resilient part that is attached to a base end of the rigid part. A disk-facing surface of the arm is arranged within the total of thicknesses of the rigid part and head.

Dependent claims

A head suspension for a hard disk drive, comprising:

an arm to be attached to a carriage of the hard disk drive and turned around a spindle;
a load beam including a rigid part and a resilient part, to apply load onto a head that is arranged at a front end of the load beam to write and read data to and from a disk arranged in the hard disk drive, a base end of the rigid part being connected to the resilient part that is supported with the arm;
and
a flexure having read/write wiring patterns connected to the head, the flexure supporting the head and attached to a surface of the rigid part that is oriented toward the disk,
the flexure and the resilient part that are integral with or independent of each other being fixed to a surface of the arm that is oriented opposite to the disk.
