    摘要： A thermally actuated head for magnetic head for magnetic data recording having a contact sensor for detecting contact between the head and a magnetic disk. The contact sensor includes a thermal sensor film and first and second leads, wherein the leads extend at least as far from the ABS as the thermal sensor film. More preferably the leads extend slightly further from the ABS than the sensor film so that contact between the magnetic disk and the contact sensor occurs at the leads rather than at the sensor film. The sensor film can be constructed of NiFe, preferably having 30-70 atomic percent Ni or more preferably 40-60 atomic percent Ni or most preferably 40-50 atomic percent Ni. The leads are preferably constructed of one or more of Ru, Rh or Ta or an alloy whose primary constituents are Ru, Rh or Ta.

    摘要： A head for magnetic thermally assisted magnetic data recording, having a read element, a write element a heater element for controlling thermal protrusion of the read and write elements and a thermal sensor for detecting contact a portion of the head with a magnetic media. The thermal contact sensor is arranged so that the thermal conduction between the thermal contact sensor and the read element is substantially equal to the thermal conductivity between the thermal contact sensor and the write element. In this way the accuracy of the detection of thermal contact is maintained whether the read element makes contact with the disk or the write element makes contact with disk.

    摘要： Embodiments of the invention improve the power consumption and response speed of a heater for the gap flying height (hg) adjustment, to minimize an influence that the heater has on a life of a read element, and to provide a heater having resistance lines reduced in breaking and ensuring higher reliability. In one embodiment, a read/write element is formed near an air bearing surface (ABS) on a slider, and the circumference of the read/write element is filled with alumina. The read/write element includes an upper magnetic pole piece, a lower magnetic pole piece, a coil, and a resist filling around the coil, and a read element (MR) for performing reading, and an upper shield and lower shield for protecting the read element from an external magnetic field. A heater for adjusting the flying height is provided between the slider and the read/write element but near the read/write element. A temperature gradient relaxing material having a thermal conductivity higher than that of the heater and that of a material (alumina) filling around the heater is formed near the heater.

    摘要： Image forming apparatus (100) creates a toner pattern on intermediate transfer belt (11) as a preprocessing of gradation correction, and calculates a cycle at which density unevenness is largest. Then, a toner image for gradation correction is formed so as to cancel cyclic unevenness at a cycle at which the largest density unevenness occurs. As a result of this, it becomes possible to suppress the deterioration of density detection accuracy and perform a highly accurate gradation correction even if density unevenness of any cycle occurs.
