|20130223008||MOLDED HEAT SINK AND METHOD OF MAKING SAME - A heat sink for use with a heat generating component includes a molded cooling block including a molded cooling passage for receiving a cooling medium. The cooling block is configured to be positioned in sufficient heat transfer relationship with respect to the heat generating component so that the cooling medium is able to receive heat from the heat generating component. Furthermore, the cooling block includes first and second sections that are connected together and that each partially define the cooling passage.||08-29-2013|
|20120232843||METHODS FOR CHARACTERIZING VIBRATION OF A RACK STRUCTURE - A system for characterizing vibration of a rack structure having at least one hard disk drive disposed therein and a vibration exciter operatively associated with the rack structure includes one or more computers. The one or more computers are configured to command the vibration exciter to provide vibration input to the rack structure and to command a plurality of reads from the at least one hard disk drive such that, for each of the plurality of reads, data stored on the at least one hard disk drive is retrieved from the at least one hard disk drive. The one or more computers are also configured to obtain read rate information related to the plurality of reads and to identify at least one resonant frequency of the rack structure based on the read rate information.||09-13-2012|
|20120206833||Method of Positioning a Transducer with a Magnetically Preloaded Linear Guide - A transducer positioning apparatus is provided that supports a read/write head on a data storage machine and biases the head against rotation. The transducer positioning apparatus may comprise a base that includes a linear drive motor and a support frame to which the read/write head is secured. The support frame is reciprocally driven by the linear drive motor relative to the base. A magnetic coupling is provided between the base and the support frame that resists movement of the frame other than the reciprocal movement of the support frame relative to the base. A method is also disclosed for magnetically biasing a movable head of a transducer against rotation.||08-16-2012|
|20110298567||SYSTEM AND METHOD FOR CONSTANT CHARACTERISTIC IMPEDANCE IN A FLEXIBLE TRACE INTERCONNECT ARRAY - A system for matching impedance in a flexible trace interconnect array. The array comprising a flexible dielectric film, a plurality of trace conductors disposed along a longitudinal axis of the dielectric film, and a shield disposed along a section of the array, wherein at least one parameter of at least one of an unshielded section and of the shielded section is selected such that impedance of the unshielded section and impedance of the shielded section are substantially the same.||12-08-2011|
|20110211278||METHOD OF RETAINING A TRANSDUCER ON A BASE - A method of retaining a transducer for a digital storage apparatus that reads and writes data to a tape as the tape is moved in a tape drive path across the transducer. According to the method a head assembly is attached to the base to be movable relative to the base in a linear path that is perpendicular to the tape drive path. Movement of the head assembly is guided on a track that is partially defined by the head and partially defined by the base. At least two balls are disposed in the track between the base and the head assembly. A magnetic coupling retains the balls within the track. A linear motor operatively engages the head assembly to move the head assembly to follow the tape.||09-01-2011|
