Abstract: A slider includes a void for controlling the flying height of the slider over a disk in a HDD. The slider comprises a slider body having a leading surface and a trailing surface. A read/write element is formed in a portion of the slider body proximate to the trailing surface of the slider body and a first thermal heater proximate the read/write element, wherein a first void is defined within the slider body proximate to the read/write element for increasing a mobility of the read/write element to increase the protrusion when thermal energy is introduced to the read/write element.

Abstract: The invention provides a magnetic head slider and a magnetic disc drive which can position at a high precision and in a simple manner. A magnetic head slider (4) includes a recording and reproducing element (20) writing and reading data, a heat generating element (21) arranged at least in one side of directions (that is, a width direction of the magnetic head slider (4)) corresponding to a width direction of a recording track with respect to the recording and reproducing element (20), and generating heat on the basis of a current application, and a member (25) interposed at least between the recording and reproducing element (20) and the heat generating element (21) and expanding in correspondence to the heat generation of the heat generating element (21).

Abstract: A magnetic head slider having a thermal microactuator capable of efficiently transmitting thermal expansion displacement in the vicinity of a heating element to the region of a read/write element and thereby enabling high-speed displacement response is realized. The magnetic head slider comprises a slider substrate and a thin film stack part formed on the slider substrate. The thin film stack part includes a read/write element for reading and writing data and one or more heating elements arranged on one side or on each side of the read/write element in regard to a direction corresponding to the track width direction for generating heat in response to energization. Further, a low Young's modulus layer (made of a material having a low Young's modulus or void) is arranged between the slider substrate and the thin film stack part.

Abstract: In a discrete track medium and a patterned medium, a meniscus adsorptive force is reduced and writing into adjacent tracks is prevented. A magnetic layer in lands or patterns in the discrete track medium or the patterned medium is formed into a cylindrical shelly or spherical shelly shape with a uniform thickness. Moreover, a height of cylindrical shelly land or a height of spherical shelly land is changed between 5 nm and 30 nm according to radial positions. Thus, an effect is achieved for providing a magnetic recording medium and a magnetic disk apparatus which are excellent in realizing higher recording density and higher reliability.

Abstract: There is provided a head suspension mechanism capable of more effectively restraining sway mode and second-order torsion mode vibrations of the head suspension mechanism caused by an air flow. A flange portion having a free end portion 23c on the base part side is formed at both edges close to the tip end of a suspension main frame 23, and at the same time, an elastic material 23d is provided in the free end portion 23c. Also, a sway mode dynamic vibration absorber is formed by the length of the flange portion and the damping effect of the elastic material 23d.
