  • Patent number: 10438617
    Abstract: A magnetic write head for heat assisted magnetic recording having a novel heat sink structure. The write head includes a magnetic write pole and a thermal transducer located adjacent to a leading edge of the magnetic write pole. A heat sink structure, constructed of a non-magnetic, thermally conductive material such as Au, Ag or Cu partially surrounds the magnetic write pole. The heat sink structure can be formed to contact first and second sides of the magnetic write pole, and can be recessed from the media facing surface of the write head. The space between the heat sink structure and the media facing surface can be filled with a physically hard, non-corrosive metal.

  • Patent number: 10403315
    Abstract: Embodiments disclosed herein generally relate to a HAMR head. The HAMR head includes a main pole, a waveguide and a NFT disposed between the main pole and the waveguide. The NFT includes an antenna, and the antenna includes a first portion and a second portion. The second portion may be made of a material having a higher melting point than the material of the first portion. Having the second portion helps reduce the temperature rise of the NFT and reduce the laser power applied to the NFT.

  • Publication number: 20190265618
    Abstract: An image forming apparatus connected to a charging device includes an image forming unit, a fixing unit, a charge processor, a controller, and a printed sheet counter. The charge processor charges a fee for printing. The controller selects an energy saving mode, upon deciding that a balance of a deposited amount in the charging device is less than a threshold amount. The printed sheet counter counts the number of sheets of the recording medium printed by the image forming unit in one single printing job. The controller selects the energy saving mode for the next printing job, upon deciding that the number of sheets printed in one single printing job is less than a predetermined threshold number of sheets, when the deposit balance is remaining in the charging device.

  • Patent number: 10360932
    Abstract: A method for manufacturing a magnetic write head having a heat sink structure, wherein the magnetic write head is free of voids at the media facing surface. After forming the write pole, a chemical mechanical polishing process is performed prior to defining the heat sink structure. Planarizing the write pole structure by chemical mechanical polishing prior to forming the heat sink structure advantageously reduces the topography over which the heat sink structure. This mitigates shadowing effects from the write pole structure and prevents the formation of voids at the media facing surface.
