摘要： In a beam irradiation device, laser light emitted from a laser light source is entered into a mirror. An actuator pivotally moves the mirror into which laser light is entered, whereby a targeted area is scanned with the laser light. Servo light emitted from a semiconductor laser is entered into a hologram element. The hologram element is pivotally moved with the pivotal movement of the mirror. A diffraction pattern is formed on an exit surface of the hologram element. A photodetector receives servo light transmitted through the hologram element to output a signal depending on a light receiving position of the servo light. The scan width of servo light on the photodetector is increased by a diffraction function of the hologram element.

摘要： An information recording and reproducing device diffracts by a diffracting means (14) to make laser light separated into a main beam and a sub-beam, irradiates evanescent light in relation to the main beam, by an evanescent light generating means (21), to a track where a recording pit provided on a recording surface of a recording medium is formed and also irradiates evanescent light in relation to the sub-beam to be separated to a track where no recording pit provided on the recording surface of the recording medium is formed. A moving means (210) moves the evanescent light generating means to a direction to change a gap with the recording surface. Further, a judging means (40) judges an uneven state of the recording pit formed on the recording medium, a signal generating means (3161) generates a gap error signal from a signal indicative of a return light amount in relation to the sub-beam or the main beam in accordance with the result, a control means (315) controls the moving means in accordance with a gap error signal so as to make the gap become a target value in response to the uneven state to be judged.

摘要： The present invention provides a thin film magnetic head capable of satisfying both assurance of recording performance and assurance of reproduction performance. In the case where a lower magnetic layer is formed of an iron cobalt alloy (for example, Fe65Co35) which contains iron in a range of 60 at % to 80 at % and has extremely high saturation magnetic flux density of 2.4 T or higher, a head isolation layer formed of ruthenium (Ru) is provided between the lower magnetic layer and an upper read shield layer portion. As compared with the case where the head isolation layer is not provided between the lower magnetic layer and the upper read shield layer portion, the strength of a recording magnetic field increases and a reproduction output of an MR element is stabilized.

摘要： A scan trajectory of a laser beam is controlled based on external signals each related to a driving direction and a driving speed, a result obtained by detection of an obstacle, and signals related to distances to the obstacle. For example, at the time of a right turn, a scan trajectory for increasing scan frequency on a portion shifted in a right-turn direction from a center axis in a driving direction is set. At the time of high-speed driving, a scan trajectory for increasing scan frequency on a center portion in the driving direction is set. When the obstacle is detected at a position corresponding to a distance shorter than a threshold distance, a scan trajectory for increasing scan frequency in the vicinity of the obstacle is set. Detection of the obstacle and monitoring of a state thereof are adequately and smoothly performed at the time of changing of the driving direction, the time of high-speed driving, and the time of detection of the obstacle.
