Abstract: Methods to provide a ramp to remove a read/write head connected with a suspension from a media in accordance with the present invention can comprise calculating a grade of one or more surfaces having a plurality of progressively shallower grades. A transition between a steep grade and a less steep grade can occur at a nominal location at which the read/write head is removed from communicative proximity with the media. By shaping a ramp such that it includes a maximum steep grade, a surface of the media can have an optimized data region, potentially increasing the spacing of tracks or alternatively increasing the capacity of the media.

Abstract: Assemblies in accordance with the present invention can access a data storage medium having one or more disks. One such assembly comprises a mounting block including a bore and spacer, an arm stack connected with the top surface of the spacer, and a bottom arm connected with the bottom surface of the spacer. The arm stack comprises module(s) stacked on a top arm. The arm stack and bottom arm are designed such that either can be disconnected from the mounting block without disassembling the bore. By having a removably fastened arm stack and bottom arm, the assembly can be built at a relatively low cost without deformation. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Abstract: In a disk drive including a conventional head and disk assembly containing a spindle motor for rotating a disk hub at a constant angular velocity and at least one rotating disk mounted to the hub, apparatus comprising a base having a peripheral sidewall surrounding the base. The base supports the head and disk assembly within an interior space defined by the peripheral sidewalls in combination with the base. To reduce the power consumption as well as the operating temperature of the disk drive by controlling and confining the air mass proximate the disk, a shroud is positioned within the interior space and proximate the disk such that the shroud substantially circumscribes the circumference of the disk for an arc of approximately 320 degrees.
