  • Patent number: 10121504
    Abstract: A tape head having offset transducer spans between adjacent modules of the tape head that serves to maintain the balance between debris removal and reduced magnetic layer/recording device spacing on the one hand and reduced tape/tape head friction on the other hand. In one aspect, opposite edges of each module are relatively sharper adjacent the transducer span and relatively rounded (e.g., less sharp) away from the transducer span. The sharp edges reduce magnetic spacing loss and scrape debris off of the tape while the rounded edges reduce or eliminate contact between the tape and the head in regions where no transducer spans are present and thus where no tape writing or reading would be taking place.

    Abstract: A magnetic head includes a base, at least one magnetic transducer, at least one protection sheet, and a control circuit board. The magnetic transducer is set on an external surface of the base. The protection sheet is coupled to the external surface of the base and covers the magnetic transducer. The protection sheet covering the magnetic transducer prevents the magnetic transducer from direct exposure. The control circuit board is coupled to a bottom of the base and electrically connected to the magnetic transducer. The control circuit board may be electrically connected with a predetermined control device so that the control circuit board receives a read signal transmitted from the magnetic transducer and transmits the read signal to the predetermined control device. As such, using the magnetic transducer to read data may simplify the conventional magnetic head in respect of complicated components, size, manufacturing time, labor, and cost.

  • Publication number: 20100110587
    Abstract: A planar write module and a hybrid planar write-vertical read bidirectional tape head comprising the write module and one or more vertical read modules. The write module has a write module tape bearing surface for engaging the magnetic recording tape. Plural write elements in the write module each comprise plural thin film layers oriented in generally parallel planar relationship with the write module tape bearing surface. The write elements are arranged so that the transducing gaps of adjacent write elements are generally aligned in a direction that is transverse to a streaming direction of the magnetic recording tape. Each read module has a read module tape bearing surface for engaging the magnetic recording tape. Plural read elements in the one or more read modules each comprise plural thin film layers oriented in generally perpendicular relationship with the read module tape bearing surface.

  • Patent number: 7675710
    Abstract: A tape drive for reading both new technology tapes and legacy tapes. The tape drive includes a three bump head with two outer read bumps and an inner write bump. The outer read bumps include readers for reading data from tracks of a first width on a first storage tape while the inner write bump includes writers for writing data in tracks of the first storage tape. Legacy readers are provided in the head to read data from tracks of a second width that is greater than the first track width on a second storage tape. The legacy readers are provided by piggybacking or merged-pole techniques in the inner write bump or are provided in one or both of the outer read bumps. The tape drive includes control circuitry with channels for processing data signals from the narrower readers and channels for processing data signals from the wider legacy readers.

  • Patent number: 7570457
    Abstract: A magnetic recording head is provided comprising a flat contour head having a deposited closure. An ion-milled trench or recess is provided near the substrate edge to create a lip or wear zone between the trench edge and the substrate/gap interface. As the tape passes over the head, the lip begins to wear and acquires a bevel. After up to a few hundred hours of runtime, the bevel spans the entire length of the lip after which the bevel length remains constant resulting in a constant rate of head wear. The width of the lip or wear zone is chosen such that head wear chases gap and transducer wear resulting in reduced recession of the transducer from the recording tape.

  • Publication number: 20090109570
    Abstract: A magnetic device includes a write element having a write element tip that defines a medium confronting surface. The write element is operable to generate a first field at the medium confronting surface. A conductor is proximate the write element tip and first and second conductive leads are connected to the conductor and configured to deliver a current to the conductor to generate a second field that augments the first field. First and second side elements are disposed on opposite sides of the write element tip in a cross-track direction at the medium confronting surface. At least a portion of the first conductive lead is disposed adjacent the first side element on a side opposite the medium confronting surface, and at least a portion of the second conductive lead is disposed adjacent the second side element on a side opposite the medium confronting surface.

  • Patent number: 7505221
    Abstract: Data tracks are written across a width of a tape by positioning a first head section across the tape and writing a first subset of data tracks onto the tape with a first plurality of write elements on the first head section. A second head section is positioned across the tape separately from the first head. A second subset of data tracks is written onto the tape with a second plurality of write elements on the second head section so that the second subset is interleaved with the first subset. A third head section is positioned across the tape separately from the first head and the second head. The first subset and second subsets are read with a plurality of read elements on the third head section to verify that data was correctly written onto the tape.

  • Patent number: 7477482
    Abstract: A filled-gap magnetic recording head is provided comprising a flat or cylindrical contour head having a row of magnetic transducers in a gap region disposed between a rowbar substrate and a closure. The gap region is intentionally recessed to have a predetermined recess profile below a tape support surface. An electrical insulation layer is deposited on the tape support surface and on the recess profile of the gap region. The insulation layer prevents electrical shorting between the magnetic transducers and other conductive elements in the gap due to accumulations of conductive debris from the magnetic recording tape. A method of making the filled-gap magnetic recording head by intentionally recessing the gap region, cleaning the recessed profile and depositing an insulator layer is provided.
