Abstract

Embodiments of disk drive head suspensions are described that include a spring metal layer. The spring metal layer includes a base region, support arms extending from the base region, and a slider mounting region. The slider mounting region includes a proximal portion, a distal portion, and a pair of motor openings. The motor openings are configured to receive motors such that the longitudinal axes of the motors are non-parallel with the longitudinal axis of the slider mounting region. The suspensions include traces that include a base portion on the base region of the spring metal layer, a spring metal-unsupported portion extending from the base region to the slider mounting region, and a slider mounting portion extending from the spring metal-unsupported portion onto the slider mounting region. And, the suspensions include an insulating layer between portions of the spring metal layer and the conductor layer.

First claim

What is claimed is:

1. A method of manufacturing a disk drive suspension comprising:
attaching a flexure to a load beam, the flexure having a flexure longitudinal axis and one or more flexure motor openings,
each of the one or more flexure motor openings having a motor longitudinal axis that is non-parallel with the flexure longitudinal axis,
each of the one or more flexure motor openings is configured to receive a motor at a first terminal pad and at a second terminal pad, the first terminal pad and the second terminal pad are positioned within each of the one or more flexure motor openings,
the load beam including one or more motor openings, at least as large as the one or more flexure motor openings, such that one or more locations of the one or more motor openings of the load beam correspond to one or more locations of the flexure motor openings of the flexure; and

mounting one or more flexure motors to the flexure through the one or more motor openings of the load beam.

2. The method of claim 1 further comprising mounting the load beam to a baseplate, the baseplate including one or more motor mounts configured to receive a baseplate motor.

3. The method of claim 2 further comprising mounting one or more baseplate motors to the one or more motor mounts.

4. The method of claim 3 , wherein mounting one or more flexure motors to the flexure through the one or more motor openings of the load beam and mounting one or more baseplate motors to the one or more motor mounts are performed on the same side of the disk drive suspension.

5. The method of claim 4 , wherein mounting one or more flexure motors to the flexure through the one or more motor openings of the load beam and mounting one or more baseplate motors to the one or more motor mounts are performed at a same stage of a manufacturing process.
