摘要： There is provided a thermally assisted magnetic recording device capable of preventing collision between a thermally assisted magnetic recording head and a disk due to thermal deformation of a near-field transducer. The thermally assisted magnetic recording device includes a temperature sensor for measuring the temperature in the vicinity of the near-field transducer, a table that stores the relationship between temperature and deformation in the vicinity of the near-field transducer, and a control unit. The control unit calculates the deformation in the vicinity of the near-field transducer, from the temperature measured by the temperature sensor and the relationship between temperature and deformation stored in the table. Then, the control unit drives the flying height control actuator according to the calculated deformation to control the distance between the thermally assisted magnetic recording and the disk in order to avoid contact between them.

摘要： A thermally assisted magnetic recording head is formed of a slider and a magnetic head. The magnetic head includes a main pole, a reader, a coil, a near-field transducer, and a waveguide. A metal film with high thermal conductivity is formed at both sides of the near-field transducer in a width direction of the magnetic head. The use of the metal film as a radiator plate ensures to prevent the temperature of the near-field transducer from becoming locally high.

摘要： A thermally assisted magnetic recording head with highly efficient optical coupling, while guiding a laser beam from a semiconductor laser element, i.e., a light source, to a leading end thereof, eliminating an influence due to heat generated by the element, and having excellent floating characteristics. The thermally assisted magnetic recording head includes a substrate 2 having a first optical waveguide 1, a semiconductor laser element 100, and a slider 4 having a second optical waveguide 3 formed on an end surface. The semiconductor laser element 100 is fixed on the substrate 2 so that light emitted from the element 100 propagates through the first optical waveguide 1 and a slider 4 is fixed on the substrate 2 so that light emitted from the first optical waveguide 1 propagates through the second optical waveguide 3. High optical coupling efficiency is then achieved, while ensuring both heat-dissipating and floating characteristics.

摘要： Provided is a magnetic head slider apparatus that can minimize a change in a roll angle caused by an impact force even with a submount mounted on a side surface thereof and achieve steady flying with the roll angle minimized. A dimple position and a pressure center position of a lifting force are moved in a slider width direction to thereby align a center of mass of a slider having a submount including a laser diode mounted on a side surface thereof, the dimple position, and the pressure center position of the lifting force with each other. This provides a magnetic head slider and a suspension thereof, and a magnetic disk drive apparatus offering higher recording density and higher reliability.

摘要： A slider including a magnetic head part, an optical waveguide, and a near field element is fixed by first and second adhesives to a submount on which a semiconductor laser and a mirror are mounted, the mirror being placed at one end of the semiconductor laser in a resonance direction thereof and reflecting a laser in a direction intersecting with the resonance direction. At this time, at least parts of the first and second adhesives are applied to a position opposed to the semiconductor laser with an intermediation of the submount. The first adhesive having a higher Young's modulus than that of the second adhesive is applied onto an inflow end side of the slider including a solder connection portion, the second adhesive being applied onto an outflow end side of the slider.
