摘要： A measuring circuit system in a magnetic field measuring apparatus of the invention has an amplifier and a band-pass filter connected in sequence on an output terminal side of the TMR element, the band-pass filter is a narrow-range band-pass filter such that a peak pass frequency of the filter that is a center is a basic frequency selected from a range of 10 to 40 GHz and a band width centered around the basic frequency is a narrow range of ±0.5 to ±4 GHz; and with the measuring circuit system, an SIN ratio (SNR) of 3 dB or greater is obtained, the SNR being defined by a ratio of an amplitude S of a high-frequency generated signal induced by the TMR element to a total noise N that is a sum of a head noise generated by the TMR element and a circuit noise generated by the amplifier. With such a configuration, an in-plane high-frequency magnetic field generated by a microwave-assisted magnetic head is reliably and precisely measured.

摘要： A method is provided to enable efficient optimization of write pulse waveforms using a trial writing region. To record information on an optical recording medium using a laser beam, the method includes: recording a specific pattern of multiple record marks on the trial writing region of the optical recording medium; decoding a read signal from the specific pattern using a PRML detection method; and tuning a write pulse waveform for forming the record marks based on the quality of decoded data determined by the PRML detection method.

摘要： When the recording capacity of an optical recording medium is increased, both reproduction characteristics and a tilt margin are improved. Specifically, when a laser beam is projected onto an information recording layer of the optical recording medium to reproduce information, a laser beam having a wavelength of 400 to 410 nm is employed. In addition, an objective lens which converges the laser beam and has a numerical aperture NA of 0.70 to 0.90 is employed. The reproduction is started by projecting the laser beam. A reproduction signal obtained by projecting the laser beam is decoded by means of a PRML detection method to generate reproduction data of the optical recording medium. When the quality of the reproduction data deteriorates, the power of the laser beam is temporarily increased.

摘要： The invention aims to prevent inadvertent rewriting or erasure of servo information in a patterned medium based on the perpendicular recording mode. The magnetic recording medium of the invention includes recording tracks each having an array of unit minute recording portions of a magnetic material separated by non-recording portions of a nonmagnetic material. The recording tracks include data regions and servo regions. The unit minute recording portions in the data regions have substantially the same surface area as the unit minute recording portions in the servo regions. The invention satisfies ARS/ARD≧1.5 provided that the unit minute recording portion has an aspect ratio which is the thickness divided by the square root of the surface area, the unit minute recording portion in the data region has an aspect ratio ARD, and the unit minute recording portion in the servo region has an aspect ratio ARS.
