摘要： A method using directed self-assembly of BCPs enables the making of a master disk for nanoimprinting magnetic recording disks that have patterned data islands and patterned binary encoded nondata marks. The method uses guided self-assembly of a BCP to form patterns of sets of radial lines and circumferential gaps of one of the BCP components, which can be used as an etch mask to make the master disk. The sets of radial lines and circumferential gaps can be patterned so as to encode binary numbers. The pattern is replicated as binary encoded nondata marks into the nanoimprinted disks, with the marks functioning as binary numbers for data sector numbers and/or servo sector numbers. If the disks also use a chevron servo pattern, the binary numbers can function to identify groups of tracks associated with the chevron servo pattern.

摘要： A method for making a master disk for nanoimprinting patterned-media magnetic recording disks has patterns for both the data islands and the nondata regions. The method uses guided self-assembly of a block copolymer (BCP) to form patterns of generally radial lines and/or generally concentric rings as well as patterns of gap regions of one of the BCP components. The pattern of lines and/or rings have the BCP components aligned as lamellae perpendicular to the substrate, while the pattern of gap regions has the BCP components aligned as lamellae parallel to the substrate. One of the BCP components is removed, leaving the other BCP component as an etch mask to fabricate either the final master disk or two separate molds that are then used to fabricate the master disk.

摘要： A patterned-media magnetic recording disk drive uses an optical system for clocking the write data and a patterned-media disk that has discrete magnetizable data islands with nonmagnetic spaces between the islands, wherein the nonmagnetic spaces contain optical contrast material. The optical contrast material may be optically absorptive material, fluorescent material, or a metal layer that generates surface plasmons when excited by radiation of a specific wavelength. Radiation from a primary radiation source is directed to a near-field transducer maintained near the disk surface and a radiation detector detects radiation reflected back from the transducer. If the disk has fluorescent material or a metal layer in the nonmagnetic spaces, then a secondary radiation source irradiates the fluorescent material or metal layer with radiation of a specific wavelength to cause the fluorescent material to emit radiation or the metal layer to generate surface plasmons. As the disk rotates, reflected optical power from the transducer varies depending on whether an island or space is under the transducer. The output signal from the radiation detector output controls the write clock.

摘要： Monitoring time-dependent displacement of a membrane in an electrostatic acoustic device. An oscillator is configured to produce a probe signal varying at radio frequency. The probe signal is symmetrically coupled into the first and second electrodes. DC bias voltages are symmetrically applied to the first and second electrodes. A voltage signal from the membrane is sensed and input at a high pass filter input. A multiplier is configured to input the filtered signal modulated at radio frequency and portion of the probe signal. The multiplier is configured to output a multiplied signal which is demodulated to produce therefrom an audio output signal responsive to the time-dependent displacement of the membrane.

摘要： A patterned perpendicular magnetic recording disk has a pre-patterned disk substrate with pillars and trenches arranged in data regions and servo regions. In the data regions, the height of the data pillars is equal to or greater than the spacing between the data pillars, while in the servo regions the height of the servo pillars is less than the spacing between the servo pillars. A magnetic recording material with perpendicular magnetic anisotropy is deposited over the entire disk substrate, which results in magnetic material on the tops of the data pillars and servo pillars and in the servo trenches. The material in the data trenches is either nonmagnetic or discontinuous. After the application of a high DC magnetic field in one perpendicular direction and a low DC magnetic field in the opposite direction, the resulting disk has patterned servo sectors with servo pillars all magnetized in the same perpendicular direction and servo trenches magnetized in the opposite perpendicular 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.
