20140233131 | PROTECTING INFORMATION WRITTEN TO RECORDING MEDIUM - A data storage device can include a recording medium; a controller unit to generate control signals in response to write information and write commands; and a transducer section coupled to receive the controls signals, and in response, write the write information into the recording medium and form a data protection pattern in the recording medium adjacent to the write information. | 08-21-2014 |
20140122747 | CONTROLLER, DATA STORAGE DEVICE, AND DATA COMMUNICATION SYSTEM HAVING VARIABLE COMMUNICATION SPEED - Apparatuses having variable communication speeds are disclose. In one example, an apparatus may comprise a controller configured to: receive a signal from a host, the signal being compatible with a data communication protocol at a first data communication speed; selectively implement a first data communication protocol from a plurality of data communication protocols to communicate with a first memory or implement a second data communication protocol from the plurality of data communication protocols to communicate with a second memory based on the data communication speed; store data in the first memory via the first data communication protocol when the data communication speed is a first speed; and store data in the second memory via the second data communication protocol when the data communication speed is a second speed that is different than the first speed. | 05-01-2014 |
20130143073 | Perpendicular Magnetic Recording Layer with Regions Having Different Magnetic Anisotropy Constants - An apparatus having a recording layer of a magnetic material with a concentration of implanted ions that increases in relation to a thickness direction of the recording layer to provide the recording layer with a continuously varied perpendicular magnetic anisotropy constant. | 06-06-2013 |
20130141816 | AIRFLOW DISPERSION SYSTEM - A hard disk drive includes a base, a disk to record and store data, a head stack assembly provided in the base to read out data from the disk which rotates about a pivot shaft, and an air force dispersion unit positioned adjacent to the head stack assembly to disperse an air force generated during a rotation of the disk. | 06-06-2013 |
20130003221 | FLY HEIGHT CONTROL USING WRITE VOLTAGE ADJUSTMENTS - Apparatus and method for controlling a fly height of a transducer adjacent a recording surface by adjusting a write voltage magnitude. In accordance with some embodiments, a write voltage with an initial magnitude is applied to a transducer. A write voltage change interval and a write voltage change amount are selected. The magnitude of the applied write voltage is thereafter successively reduced by the write voltage change amount over each of a plurality of successive write voltage change intervals. | 01-03-2013 |
20120210050 | Selection of Data Storage Medium Based on Write Characteristic - A hybrid hard disk drive includes a hard disk drive controller to receive a plurality of write commands from a host, a buffer to receive and store write data, which are input through the hard disk drive controller and correspond to each of the plurality of write commands, a command history tracker to receive the plurality of write commands and analyze a pattern of the plurality of write commands, and a CPU to control storage of the write data, which correspond to each of the plurality of write commands, on a disk or in a flash memory device based on the analysis result by the command history tracker. The drive may determine whether to store write data on the disk or in the flash memory device without operation system support. | 08-16-2012 |
