A process for assembling a storage device such as a disk drive storage device using a laser welding technique. A welding fixture holds a storage device component in a predefined three dimensional location with a small gap relative to a second component so that improved dimensional accuracy is achieved. This welding of components that do not touch allows for assembly tolerances that are independent of component tolerances. The welding fixture can use magnetic force.

In a magnetic disk drive heads are loaded and unloaded onto the magnetic disk by wings attached in close proximity to the magnetic heads. The wings ride on opposed profiles to separate the heads so that they can travel on either side of the disk and the heads are then brought together properly onto the disk. As the heads are withdrawn from the disk, they are separated by the opposed profiles and then the heads are parked on a cleaning pad.

A magnetic disk drive for writing and reading data to and from a magnetic disk contained in a cartridge which is inserted through an opening in the disk drive includes a drive motor rotated on a yoke by a manually operated shaft having a handle on one end and a cam on the other end. A flat diaphragm switch is operated by a rotation stop on the shaft to indicate when the motor is in the loaded position of engagement with the disk.
