摘要： Instead of using discontinuous step functions or pulses to drive a laser of a TAR enabled disk drive between on and off, a fixed modulation frequency may be used that alternates between a high and low laser power such that the radiation source is always delivering heat to the magnetic media when writing data to the magnetic disk. The magnetic field of the write pole may be synchronized to the modulation frequency of the radiation source to ensure that the radiation source heats the magnetic media proximate to the write pole above the grain freezing temperature when the Zeeman energy produced by the magnetic field of the write pole exceeds the thermal energy of the magnetic media.

摘要： A method and apparatus for generating a laser signal for driving a laser used in thermal-assisted recording. A channel of a hard drive generates a high-frequency component of the laser signal—e.g., a periodic wave or series of pulses—and synchronizes the phase of the laser signal with a corresponding write data signal which controls the magnetization of data bits within the magnetic disk of the hard drive. The channel may be connected to a read/write integrated circuit via a channel interconnect. The read/write circuit may include a second phase control to compensate for any phase shift and an adder circuit to combine the transmitted high-frequency laser with a DC bias. Further, the read/write circuit may include a feedback loop for adjusting the DC bias based on environmental parameters of the hard drive such as temperature.

摘要： The presented embodiments generally relate to designing an antenna of an optical transducer (e.g., a near-field transducer or near-field optical source) that focuses the optical energy of a radiation source (e.g., a laser) onto a magnetic media, thereby heating the media. Specifically, the antenna is designed to wrap-around an aperture of the optical transducer such that at least a portion of the antenna is between a main pole of a write head and a surface of the aperture that faces the main pole. Moreover, the antenna may wrap-around the aperture such that it directly contacts the main pole.

摘要： Components for, and assembly of, a thermally assisted recording device involve a laser mounted to a recording head slider. The output from the laser is directed into an optical waveguide, which delivers the laser light to the media to be written. Several challenges with thermally assisted recording are enabled by the use of a laser carrier, which holds and protects the small, relatively fragile laser and serves as a partial heat sink for the power generated by the laser. The laser, carrier and slider are bonded and can be interconnected as a unit to a suspension constituent to a hard disk drive (HDD) device.
