  • Magnetic recording head
    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.

  • Tape recording system
    Patent number: 7474498
    Abstract: A tape recording system is provided for coupling the angular velocities of a pair of roller guides disposed one on either side of a head assembly. In one embodiment, the roller guides each comprise cylindrical first and second surfaces wherein the first surfaces guide a tape over the head assembly. An idler bearing comprising a cylindrical ring having an inside diameter surface engages in rolling contact the second surfaces of the pair of roller guides, thereby coupling the angular velocities of the pair of roller guides. In another embodiment, an idler bearing comprises a roller having an outside diameter surface that engages the surfaces of a pair of roller guides on each side of the head to couple the angular velocities of the pair of roller guides.

  • PLANAR SERVO WRITE HEAD
    Publication number: 20080273264
    Abstract: A servo write head that provides fast servo pattern writing and improved tape manufacturing speed is provided. The write head may be fabricated using thin-film fabrication techniques. A coil is formed on a bottom pole of the write head. The coil has a plurality of turns that enable the write head to generate a magnetic field sufficient for writing data with reduced current. The inductance of the coil is reduced due to its small dimensions. Reduced inductance of the coil may enable increased switching frequency of the write head, allowing data to be written at a higher frequency. The write head includes a planar top pole coupled to the bottom pole. The top pole has more than one write gap is formed therein.
