摘要： A recording method suitable for high-density recording is provided to increase the reproduction quality. An optical information recording method is for recording information on an optical recording medium by irradiation of a write pulse of a laser beam to perform reproduction in a production system using a PRML detection scheme. The method includes recording a recording mark by a single write pulse, when the total length of the recording mark to be recorded and a space adjacent to the recording mark is less than a diameter of an effective reproduction spot, being 0.82×(λ/NA), where λ is a wavelength of a reproduction laser beam and NA is a numerical aperture.

摘要： A method of fabricating a magnetic head device comprising a slider having a magnetic head element, a suspension structure made of a thin resilient material and having one end supporting the slider and the other end to be attached to another member, and a head IC chip. The head IC chip is mounted on the suspension structure so as to face a magnetic recording disc and at a position spaced from the slider-supporting one end of the suspension structure by an intervening portion of the suspension structure. The position is selected so that the intervening portion is effective to suppress a temperature increase in the head IC chip due to at least thermal conduction through the intervening portion.
