20090067085 | ACTUATOR SHROUD - Devices are provided herein in a variety of examples that inhibit particle pickup and transport and mechanical vibrations and provide other advantages. In one illustrative example, an actuator assembly includes a base, an actuator disposed on the base, and a shroud disposed on the base around the actuator. The shroud includes one or more shroud walls disposed between the actuator and a flow channel exterior to the shroud. The shroud walls may include shielding walls that partially surround the actuator, radially curved shroud wall segments, fastener well shields that substantially separate an interior thereof from the actuator, and other aspects. A data storage device may have a flow path defined therein, and the shroud may be disposed around an actuator within the data storage device, providing a streamlined surface between the flow path and the actuator. | 03-12-2009 |
20090073607 | Reduction in Particle Rebound Off of Component Surfaces - An enclosure system includes an enclosure and at least one rotating storage medium positioned within the enclosure. The enclosure has a corresponding airflow contaminated with particles. An impact absorbing material is deposited on at least one component in the enclosure and positioned within and traversely to the airflow. The impact absorbing material is configured to reduce rebound velocity of the particles off of the at least one component in the enclosure. | 03-19-2009 |
20100061010 | PARTICLE DIVERTER FOR HARD DISC DRIVE - Bases for data storage systems are disclosed. Some embodiments of the bases are used in hard disc drives. Some embodiments include particle diverters. Certain embodiments of the particle diverters include a particle diverter opening adjacent to an actuator region of a hard disc drive. | 03-11-2010 |
20110205861 | LIGHT SOURCE POWER CONTROL FOR HEAT ASSISTED MAGNETIC RECORDING (HAMR) - Apparatus and method for light source power control during the writing of data to a storage medium. In accordance with various embodiments, a data recording head is provided having a magnetic transducer and a light source. The light source is driven at a first power level to irradiate an adjacent storage medium prior to the writing if data to the medium using the magnetic transducer. The first power level is insufficient to alter a magnetization state of the medium. The light source is subsequently transitioned to a higher, second power level to irradiate the storage medium during the writing of data to said medium using the magnetic transducer, the second power level being sufficient to alter said magnetization state of the medium. | 08-25-2011 |
20130064051 | Plasmonic Transducer Having Two Metal Elements with a Gap Disposed Therebetween - An apparatus includes a waveguide configured to deliver light to a transducer region. The apparatus also includes a plasmonic transducer that has two metal elements configured as side-by-side plates on a substrate-parallel plane with a gap therebetween. The gap is disposed along the substrate-parallel plane and has an input end disposed proximate the transducer region and an output end. The transducer is configured to provide a surface plasmon-enhanced near-field radiation pattern proximate the output end in response to the light received by the waveguide. | 03-14-2013 |

20140362466 | Disc Drive Apparatus with Vapor-Trapping Pathway - Various aspects of the present disclosure are directed toward a disc driver apparatus including a base, a disc drive actuator assembly, and a vapor-trapping pathway. The base, in certain embodiments, has an upwardly-facing portion with a first step and an adjacent second step that is vertically lower than the first step. The disc drive actuator assembly in some embodiments includes a pivot shaft, an E-block, and a plurality of bearings. The pivot shaft is fixed relative to the base, and the E-block has a portion facing the upwardly-facing portion of the base. The plurality of bearings designed to facilitate rotation of the E-block around the pivot shaft. The vapor-trapping pathway includes the first step and a trap region that is partly defined by the second step, the vapor-trapping pathway being designed to pass vapor flow outwardly, relative to the pivot shaft, from a level below the bearings to the trap region. | 12-11-2014 |
