  • Patent number: 8416537
    Abstract: In one embodiment, a read sensor for a recording head for a magnetic media storage system, has first and second shields, and a magneto-resistive sensor disposed between and shielded by the first and second shields in which the sensing axis of the sensor is tilted with respect to the recording surface of the head. In one embodiment, the sensing axis is oriented at an angle between 10 and 60 degrees with respect to the normal of the recording surface. Other embodiments are described and claimed.

  • Patent number: 8270108
    Abstract: A method, system and computer-usable medium are disclosed for performing data write and data read operations on a tape storage medium. A dual head/tape actuator assembly, comprising two head/tape actuator assemblies, is implemented to perform data write and data read operations on a tape medium. Each of the head/tape actuator assemblies comprises a set of data writer elements and a set of data reader elements. During data write operations, the data writer elements on one head/tape actuator assembly are used to write data to a tape medium and the data reader elements on the other head/tape actuator assembly are used to read the data from the tape medium. During read operations, half of the data readers on one head/tape actuator assembly are used to read data from half of the written data tracks on the tape medium and half of the data readers on the other head/tape actuator assembly are used to read the other half of the written tracks.

  • Patent number: 6344952
    Abstract: A read element for a tape drive system is disclosed. The read element generally comprises a magneto-resistive sensor electrically coupled to first and second leads and at least one electrically conductive magnetic shield proximate the magneto-resistive element. A resistor is electrically connected to the conductive magnetic shield and to one or more of the first and second leads. The resistor is disposed between the first and second leads. The resistor continuously discharges electric charge that builds up on the conductive magnetic shield. The resistor typically has a resistance that is large enough to protect against noise due electrical shorting of the conductive magnetic shield and small enough to prevent a build-up of electric charge on the shield.

  • Patent number: 5552589
    Abstract: A magnetic assembly for detection and authentication of magnetic documents. The magnetic assembly includes a permanent magnet (PM), first and second magnetically soft high permeability pole pieces shaped to form a tapered, variable gap size magnetic circuit with the permanent magnet. The PM is located at a first gap between the first and second pole pieces. A magnetoresistive (MR) sensing element is located at or near the center of a second gap between said first and second pole pieces. The second gap and MR sensing element are proximate a magnetic document to be sensed.
