  • Patent number: 5965041
    Abstract: 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.

  • Patent number: 5768059
    Abstract: 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 As the heads are withdrawn from the disk, they are separated by the opposed profiles and then the heads are parked on a cleaning pad.

  • Patent number: 4746580
    Abstract: A method of making read-only magnetic recording media by the use of photolithographic/photoresist techniques, and the vacuum deposition of discrete bits of a high coercivity metal, followed by magnetization of said metal. A nonmagnetic substrate is covered by a layer of photoresist and a layer of high coercivity magnetic material. Selective light-pattern exposure of the resist, followed by layer-removal-procedures, cause the substrate to be covered by islands of hard magnetic material, in the pattern of a desired data track. The substrate is then subjected to the influence of a steady-state magnetic field in order to convert the metal islands into a read-only data pattern which can be read by a magnetic head. A floppy disk of this type is used to stress-test the head placement of floppy disk drives.

  • Patent number: 4663677
    Abstract: 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.

  • Patent number: 4456938
    Abstract: During manufacture of a flexible disk drive, the drive's head is located in its penetration, radial, azimuth, tangential, roll and pitch attitudes by reading a test disk, as the head is held by a robotic head holder/manipulator. The head's signal produces closed-loop control of a serially-stacked array of rotary and linear motors which position the holder/manipulator. After the head is properly adjusted, it is fixed to the disk drive's head carriage.
