US Patent:

6459545, Oct 1, 2002

Filed:

Mar 14, 2000

Appl. No.:

09/524147

Inventors:

Todd L. Graves - Garland UT
Wayne A. Sumner - Ogden UT

Assignee:

Iomega Corporation - Roy UT

International Classification:

G11B 2303

US Classification:

360133, 369291

Abstract:

A data storage cartridge for a data storage disk drive has a marker including a latent illuminance material such as phosphor. A matte material on the cartridge or within the marker diffusely reflects charging light that is not absorbed by the latent illuminance material in the marker. This reduces noise and signal pollution in the light then emitted by the latent illuminance material. Accordingly, an accurate decay time can be determined. The decay time is checked to provide identification of different types or generations of data storage cartridges or provides a secure keying mechanism for authorized access to proprietary software.

US Classification:

073/001110, 073/001080, 324/202000, 324/210000

Abstract:

A device for calibrating drag test drives comprises a disk drive unit, a non conductive, non magnetic disk, and a magnet placed substantially planar to the non magnetic disk wherein the disk can spin in the disk drive through a magnetic field produced by the magnet. The device also comprises a current measuring device wherein the device measures the amount of current the disk drive motor draws while spinning the disk.

Appl. No.:

8/752823

Inventors:

Wayne A. Sumner - Ogden UT

Assignee:

Iomega Corporation - Roy UT

International Classification:

G11B 2303

US Classification:

360133

Abstract:

A cartridge for a disk drive has a rigid shell with two keying grooves along the top and bottom edges of one side of the cartridge. These mate with projections on the cartridge receiving slot in the drive. One of the grooves extends deeper into one planar surface of the cartridge than the other groove. This prevents insertion of the cartridge with any other orientation of the cartridge than the correct orientation.

Assignee:

International Classification:

G11B 2303

US Classification:

360133

Abstract:

A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door which opens along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

US Patent:

Filed:

Sep 7, 1999

Appl. No.:

9/390728

Inventors:

Todd L. Graves - Garland UT
Wayne A. Sumner - Ogden UT

Assignee:

Iomega Corporation - Roy UT

International Classification:

B05D 506

US Classification:

427 71

Abstract:

A system and method for applying a thick layer of luminescent emissive material, such as phosphor, to a substrate, such as a data storage cartridge, is provided whereby a luminescent emissive material is mixed with a binder, the mixture is dispensed onto a mesh screen placed over a substrate, and the mixture is then pushed through the mesh screen and applied to the substrate at a predetermined thickness. The predetermined thickness of the deposited phosphor layer is preferably between about 8 and 12 mils.
