摘要： A method for making a master mold to be used for nanoimprinting patterned-media magnetic recording disks results in a master mold having topographic pillars arranged in a pattern of annular bands of concentric rings. The ratio of circumferential density of the pillars to the radial density of the concentric rings in a band is greater than 1. The method uses sidewall lithography to first form a pattern of generally radially-directed pairs of parallel lines on the master mold substrate, with the lines being grouped into annular zones or bands. The sidewall lithography process can be repeated, resulting in a doubling of the number of lines each time the process is repeated. Conventional lithography is used to form concentric rings over the radially-directed pairs of parallel lines. After etching and resist removal, the master mold has pillars arranged in circular rings, with the rings grouped into annular bands. The master mold may be used to nanoimprint the disks, resulting in disks having a BAR greater than 1, wherein BAR is the ratio of data track spacing in the radial direction to the data island spacing in the circumferential direction.

摘要： A patterned-media magnetic recording disk drive uses an optical system for accurately clocking the write data. The disk has concentric data tracks patterned into discrete magnetizable data islands with nonmagnetic spaces between the islands. As the disk rotates, a radiation source directs near-field radiation to the islands and spaces, and a radiation detector receives reflected radiation. The radiation is directed from the source through an optical channel or waveguide on the air-bearing slider that supports the read and write heads. The optical channel or waveguide has a near-field transducer at the disk-facing surface of the slider where the near-field radiation exits and reflected radiation returns. The reflected optical power varies depending on whether the near-field transducer couples to an island or a space, so the radiation detector output signal represents the frequency and phase of the islands as the disk rotates. The write clock that controls write pulses to the write head is responsive to the radiation detector output signal, so the frequency and phase of the write clock signal can be matched to the frequency and phase of the islands as the disk rotates.

摘要： A disk drive is described having a capability of burnishing the sliders on demand by using a heater in the slider to thermally protrude the slider. Each slider includes a heating element with a sufficient thermal expansion stroke to bring the area of the slider containing the transducer into contact with the disk surface to burnish the slider. Preferably the heater is used to bring the slider into contact with the disk to burnish the lowest flying part of the slider body after the drive has been assembled, and remove most or all of the overcoat and recession, and exposing the transducers at the ABS. The burnish process is performed in situ in the drive and the drive is preferably hermetically sealed to reduce the risk of corrosion. The slider can be flown and magnetically tested prior to burnishing off the overcoat to avoid corroding the head before the drive is assembled.

摘要： A thermally-assisted perpendicular magnetic recording head and system has a head carrier that supports an optical channel for the transmission of radiation to the recording layer, a write pole for directing a magnetic field to the recording layer, and an electrical coil for inducing the magnetic field from the write pole. The optical channel has a radiation exit face with an aperture at the recording-layer-facing surface of the head carrier. The write pole has a pole tip with an end face that is recessed from the recording-layer-facing surface. The write pole tip is tapered down to the end faces. The pole tip taper and the recession of the end face concentrates the write field at the middle of the perpendicular magnetic recording layer where the radiation from the optical channel is incident. The characteristic dimension of the aperture and the spacing between the aperture and the recording layer are both less than the wavelength of the radiation. The radiation source may be a laser diode mounted to the head carrier.

摘要： A magnetic head including a media heating device that is fabricated within the magnetic head structure. The media heating device is fabricated between the writing magnetic pole of a perpendicular magnetic head and the ABS surface of the head, where it serves to heat the magnetic media during the passage of the magnetic media beneath the writing magnetic pole of the magnetic head. The media heating device includes an optical cavity resonator that can produce a high intensity near-field optical spot of subwavelength dimension at the write pole that is appropriate for perpendicular recording at 1 Tbits/in2 and beyond. Optical energy is coupled into the resonant cavity through a waveguide that is placed proximate the cavity, and optical energy is coupled out of the cavity through a post that is placed within the cavity.

摘要： A thermally-assisted recording (TAR) head for recording data in data tracks of a TAR disk is supported on an air-bearing slider and includes a near-field transducer (NFT) and an optical waveguide that directs laser light to the NFT. The NFT has an output end at the slider's air-bearing surface (ABS) located between the write pole and the optical waveguide in the along-the-track direction. A reflection layer is located on the side of the waveguide opposite the NFT. The scattered light propagated by the waveguide is reflected back by the reflection layer to the NFT. When the distance between the reflection layer and the center of the NFT in the along-the-track direction is adjusted so the phase of the reflected light matches the phase of the plasma oscillation in the NFT, the intensity of the optical near-field is increased. This allows for a reduction in laser power.
