20130086599 | OPTICAL TAPE DRIVE MOVABLE PLANARIZER SUBSYSTEM AND METHOD FOR MINIMIZING DAMAGE TO AN OPTICAL PICKUP UNIT - In an optical tape drive system, a movable planarizer subsystem includes a tape planarizer support structure for supporting an optical tape planarizer. The support structure is moveable between an operational position and a non-operational position. The movable planarizer subsystem also includes an actuator for moving the support structure and the optical tape planarizer between the operational position and the non-operational position. The operational position of the support structure positions the optical tape planarizer to permit reading/writing of information from/to an optical tape via an optical pickup unit (OPU), and the non-operational position of the support structure positions the optical tape planarizer to permit passage of a tape leader through the tape drive system without damage to the OPU. | 04-04-2013 |

20140115614 | DATA STORAGE DEVICE TAPE PATH CLEANER - A tape cartridge is provided with a reel mounted for rotation in a housing. Tape with a length, a width and a thickness, is wound upon the reel in a length direction of the tape. A leader is mounted to a free end of the tape. The leader has at least one portion with a width greater than the tape width to clean a tape path, such as a guide and/or a lens. Another tape cartridge is provided with a reel mounted for rotation in a housing. Tape is wound upon the reel in a length direction of the tape. A leader is mounted to a free end of the tape. A brush is mounted to a portion of the leader for cleaning a tape path. | 04-24-2014 |

20080209457 | DISC DEVICE - The invention provides a disc device capable of offering good SATA interface performance by optimizing the placement of the SATA connector relative to the control board, solving problems concerning noise or unnecessary radiation. | 08-28-2008 |
20080282277 | Information Processing Device - The present invention relates to an apparatus capable of optically recording information onto an information medium ( | 11-13-2008 |
20080301725 | Thermally Enhanced Disk Drive - A disk drive data storage system. The system comprises a data storage disk, a movable member positioned near the data storage disk, and a sensor assembly, supported and movable by the movable member, for writing data to and reading data from the data storage disk. The system also comprises an integrated circuit that is electrically coupled to the sensor assembly and that moves with the movable member when the movable member moves the sensor assembly. The integrated circuit comprises a face and a backside, and the integrated circuit is in a fixed physical position relative to the movable member such that the backside is oriented toward the movable member. | 12-04-2008 |
20090070794 | OPTICAL MEMBER DRIVING APPARATUS, OPTICAL PICKUP APPARATUS INCLUDING THE OPTICAL MEMBER DRIVING APPARATUS, OPTICAL DISC APPARATUS INCLUDING THE OPTICAL PICKUP APPARATUS - An optical member driving apparatus comprising: a holding member configured to have an optical member mounted thereon; a driving unit assembly configured to be capable of driving the holding member; a connecting member configured to connect the holding member and the driving unit assembly; and a jointing member configured to joint the connecting member and either or both of the holding member and the driving unit assembly. | 03-12-2009 |
20090106783 | Electomagnetic field generating element, information recording/reproducing head and information recording/reproducing apparatus - The present invention provides an electromagnetic field generating element, an information recording/reproducing head, and an information recording/reproducing apparatus. The electromagnetic field generating element makes it possible to restrain magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for use in thermally assisted magnetic field recording/reproduction using a near field. The information recording/reproducing head and the information recording/reproducing apparatus can carry out high frequency magnetic recording/reproducing. | 04-23-2009 |
20090125926 | MECHANISM FOR CONTROLLING POSITION OF OPTICAL ELEMENT - An optical element position control mechanism includes an optical element holding member which holds an optical element of a photographing system; an advancing/retracting movement guide member which guides the optical element holding member in an optical axis direction of the photographing system to be movable in the optical axis direction; and a biasing device including an arm, the arm being swingable about a swing axis which is substantially orthogonal to the optical axis and being engaged with the optical element holding member. The biasing device simultaneously exerts via the arm both a biasing force in a direction of movement of the optical element holding member that is guided by the advancing/retracting movement guide member and a biasing force in a direction orthogonal to the direction of movement of the optical element holding member on the optical element holding member. | 05-14-2009 |
20090158305 | DATA WRITING WITH PLASMON RESONATOR - A data writing system includes an array of cells for storing data and a write transducer that moves over a selected cell in the array of cells. The write transducer includes a writer producing a write magnetic field that intersects the selected cell. The write transducer also includes a plasmon resonator that is adjacent the writer. The plasmon resonator is shaped to receive lower power density radiation and to provide plasmon radiation at a higher power density to an optical spot intersecting with the selected cell. The plasmon radiation heats the selected cell above a write temperature. | 06-18-2009 |
