摘要： A flying head slider that keeps out dust particles while improving the CFH characteristics, skew dependence characteristics, and linear speed dependence characteristics for achieving a stable fly height. A flying head slider includes a positive pressure generating surface, which includes a leading pad for ensuring pitch stiffness; a pair of side pads, which are positioned behind of the leading pad and to the right and the left for ensuring roll stiffness; and a center pad, which is positioned between the side pads and controls the fly height characteristics. Furthermore, the flying head slider includes steps, which are at a lower height than the positive pressure generating surfaces and extend from the front of the slider toward side edges thereof in order to prevent dust particles from entering an area between the flying head slider and a disk surface.

摘要： Disclosed herein is a flying head slider having an air bearing surface forming portion opposed to a recording medium and adapted to receive a buoyancy produced by air bearing due to a dynamic pressure between the air bearing surface forming portion and a recording surface of the recording medium. The flying head slider includes a head for recording and/or reproducing information, a head mounting portion formed on the air bearing surface forming portion for mounting the head, and a projection of diamond-like carbon provided on the head mounting portion at the upstream side of air flow, which is along the slider, on said head. By providing the projection at the upstream side of air flow on the head, the penetration and deposition of any disturbance such as lubricant and dust to the head can be minimized to thereby prevent damage to the head. Accordingly, the operation reliability of the slider can be improved. Further, an information recording and/or reproducing device including this slider can also be provided.

摘要： A magnetic head slider mounted on a magnetic disk unit for supporting a magnetic head that writes and reads information to and from a magnetic disk is constructed such that a depth nulls1 from the surfaces of leading and trailing pads, which come into contact with a medium surface when the disk is at rest, to stepped surfaces formed on the air inflow side of the leading pads, a depth nulls2 from the contact surfaces to stepped surfaces formed on the air inflow side of the trailing pad and a step depth nulls3 from the contact surfaces to the surfaces of side rails are in a relation of nulls1nullnulls2nullnulls3. With this arrangement, the slider can follow the waved medium surface at a low flying height with a small flying height fluctuation, thus realizing high density recording, high reliability and reduced cost of the magnetic disk unit.

摘要： With a view to providing a head slider which can suppress the adhesion of dust particles to a flying surface of the head slider when the head slider flies and a disk drive employing the same head slider, a head slider in which at least an air bearing portion and a land portion for forming a vacuum area on the flying surface are provided on the flying surface of the head slider, the land portion being formed in such a manner as to have a difference in level so as to be closer by a step to a disk medium than an end surface of the slider base, wherein the water repellency of an end surface of the land portion and the water repellency of the end surface of the slider base are made higher than the water repellency of the air bearing portion. As this occurs, the water repellency of the end surface of the land portion is increased more than the water repellency of the air bearing portion, whereby the water repellency of the end surface of the slider base can be increased more than the water repellency of the end surface of the land portion.

摘要： A process to reduce step heights in planarization of thin film carriers in an encapsulation system. The improvements include using an adhesive tape having a thinner adhesive thickness and a stiffer tape for the film sealing the encapsulant on the carrier to result in a low step height surface transition between the carrier and the cured encapsulant. The composition of the encapsulant is modified to reduce the shrinkage upon curing of the encapsulant. The encapsulant may include an absorbent that absorbs the irradiation and cause the top surface to harden first compared to the bulk of the encapsulant, and/or a gas-emitting additive that creates gaseous products that expand upon irradiation to thereby reduce the shrinkage of the encapsulant upon curing. Alternatively, irradiation at very low incidence angle relative to the top surface of the encapsulant causes the top surface to harden before the bulk of the encapsulant.

摘要： A protection film is layered over the trailing or outflow end surface of a slider body in a head slider for a recording medium drive. A head element is embedded within the protection film. The head element generates heat in response to the supply of an electric current. The heat causes thermal expansion of the protection film. The tip end of the head element thus excessively approaches the recording disk beyond the medium-opposed surface of the head slider. The flying height of a protection protuberance is set smaller than a flying height of the head element even when the protection film suffers from thermal expansion. The protection protuberance is allowed to trace an orbit closer to the recording medium than the orbit of the head element. The protection protuberance is allowed to collide against obstacles on the recording medium in front of the head element.
