20110141611 | METHOD AND APPARATUS FOR MEASURING DISK RUNOUT IN A DISK DRIVE - According to one embodiment, a disk drive includes an actuator, a servo controller, and a calculation module. The actuator is configured to move the head over a disk, in the radial direction of the disk. The servo controller is configured to make the head move along a target orbit on the disk, in accordance with the distance the actuator has been moved. The calculation module is configured to calculate, as disk runout, a virtual target orbit value supplied to the servo controller to suppress the disturbance at the target orbit. | 2011-06-16 |
20110141612 | METHOD OF UNLOADING TRANSDUCER IN DATA STORAGE DEVICE AND DISK DRIVE AND STORAGE MEDIUM USING THE METHOD - Provided are a method and apparatus for performing optimum transducer unloading in a data storage device according to circumstances. The method of unloading a transducer in a data storage device comprises: determining whether a condition that requires an unloading operation is detected while the transducer is positioned on a data area on a disk; selecting, when the condition that requires the unloading operation is detected, an unloading mode corresponding to the detected condition from among a plurality of unloading modes; and moving the transducer to an area other than the data area on the disk according to the selected unloading mode. | 2011-06-16 |

20110141614 | Magnetic Head Drive Device - A magnetic head drive device including a suspension for supporting a magnetic head, and a main actuator that produces rotary movement of the magnetic head by applying current to a coil. The main actuator includes end arms each comprising a single micro-actuator, and an intermediate arm comprising two micro-actuators. The micro-actuators of the end arms are driven in the same direction, and the micro-actuators of the intermediate arm are driven in the opposite direction to the drive direction of the micro-actuators of said the arms. | 2011-06-16 |
20110141615 | MAGNETIC HEAD FOR PERPENDICULAR RECORDING - According to one embodiment, a magnetic head for perpendicular recording includes a main pole, a first soft magnetic film disposed on a trailing side of the main pole, and a first nonmagnetic film interposed between the main pole and the first soft magnetic film. A thickness of the main pole is increased in a depth direction from an air bearing surface using an inclination, and a thickness of the first nonmagnetic film increases in the depth direction from the air bearing surface. In another embodiment, an angle from a horizontal plane of an upper surface of the first nonmagnetic film is greater than an angle from a horizontal plane of a lower surface of the first nonmagnetic film in contact with the main pole. Other heads, methods, and systems are described according to more embodiments. | 2011-06-16 |
