A system for data storage including a removable memory element having a data storage device, and a docking station in communication with a host device and configured for receiving the removable memory cartridge so as to put the host system in communication with the data storage device.

Removable memory cartridge and docking station compatible with media drive expansion slots

An archival cartridge management system for conditioning removable data cartridges and normal archival operations is disclosed. The archival cartridge management system includes a cartridge holder and a controller. The cartridge holder has a connector configured for coupling to a removable data cartridge. The connector is coupled to the controller, which performs archival functions on removable data cartridges. The controller reads from removable data cartridges to determine if at least some data stored on a removable data cartridge should be refreshed. If so, the controller refreshes data stored on the removable data cartridge.

Methods and systems for laser etching of optical servo patterns on magnetic data storage media using two or more beams of laser energy produced from a single source of laser energy to produce a servo pattern on the magnetic data storage media. By using two or more etching beams, the time required to produce a servo pattern on the magnetic data storage media can be significantly reduced. Alternatively, each servo track in the servo pattern can be written more than once. The servo patterns thus formed can be read optically or they may be read magnetically using magnetic overwriting (if the servo pattern is formed in a magnetic coating on the media). In either case, the servo patterns are either permanently formed in the media when read optically, or they can be recreated after bulk erasing if they are provided using magnetic overwriting. In yet another alternative, the servo patterns may be read both magnetically and optically, with the magnetic and optical reading occurring simultaneously or sequentially.

Multibeam laser servowriting of magnetic data storage media

The present invention provides methods and apparatus for stabilizing data storage media during laser servowriting of optical servo tracks on the media. The apparatus includes a spindle for rotating the media during servowriting, a fixed media platform, and a media support for stabilizing the vertical position of the media during servowriting. The media support may include channels to reduce or control the formation of an air bearing in the area of servowriting to stabilize the vertical positioning of the media. The media support may also include a vacuum slot for drawing a vacuum through the channels.

Media stabilization for laser servowriting

A position sensor and a method of creating the same which sensor has an incoherent light source, multiple light detectors and a sinusoidal pattern that can be directly installed to the sensor. The light source and detectors are positioned along the axis of motion of the element whose position is to be determined. In a device containing such a movable target element, light from the sensor is directed through the sinusoidal pattern to and reflected from a periodic reflection profile to create detectable sinusoid signals that can be used for positioning purposes.
