Abstract: A disk drive capable of being configured into a plurality of data storage zones, wherein some of the zones have different performance characteristics than other zones; a method for performing such a zoning configuration; and, a host device utilizing such a disk drive. The disk drive comprises a disk having a plurality of sectors for storing data, a head for reading and writing the data, and a disk drive controller for controlling the head, wherein the plurality of the sectors are organized into the plurality of zones. In one embodiment of the present invention, the performance characteristics of the zones are dictated by configuration settings in the disk drive controller. The configuration settings may include settings for a plurality of parameters. In some embodiments of the present invention, the plurality of parameters comprises a CCT (command completion time) parameter, a Write Verify parameter, a Write Continuous parameter, a Read Continuous parameter, and an Error Re-allocation parameter.

Abstract: A data storage device includes a data storage media, a head, a data fetch buffer, and a controller. The head is configured to read data stored in logical block addresses (LBA) on the media. The data fetch buffer is configured to store data. The controller is configured to read data through the head from LBAs on the media that are identified by LBA access sequence information in the data storage device which identifies a sequence of LBAs that a host device will access and to store the read data in the data fetch buffer. The controller is also configured to respond to a read command from the host device that is directed to data at a LBA of the media that is identified the LBA access sequence information and which has been read into the data fetch buffer by communicating the data associated with the read command from the data fetch buffer to the host device.

Abstract: A method of forming a photographic azo or azamethine dye image in an exposed photographic silver halide element, the method of comprising the steps of (a) developing the imagewise exposed material to form an imagewise pattern of oxidized color developing agent, (b) reacting the oxidized color developing agent with a color coupler to produce an image dye, characterized in that at least one of the color developing agent and the color coupler possesses a metal chelating site such that the image dye is capable of forming a bi-, tri- or higher-dentate metallized dye, and (c) contacting the image dye with polyvalent metal ions to form a metallized dye image. Specified color developing agents include heterocyclic substituted hydrazides and specified couplers include benziso-oxazolones and 2H-pyrazolo-[3,4-b]pyridines in addition to more conventional compounds.

Abstract: Novel triazole-substituted phenylhydrazide nucleating agents are disclosed as well as silver halide photographic emulsions and elements containing silver halide grains capable of forming an internal latent image having the nucleating agents adsorbed to the surface of the silver halide grains.
