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： Described herein is a hard disk drive HDD which adopts a CSS type floating or levitation head device. A condensation sensor is provided on the inner surface of a housing or chassis. Since the capacity of the chassis is large and moisture adsorbed by the chassis due to dew condensation or the like is hard to dry, the condensation or the like produced on the inner surface side of the chassis can be detected accurately by placing the condensation sensor on the inner surface of the chassis. The condensation sensor may be attached to an arm or suspension constituting an actuator, a head slider, a flexible printed board, or a portion or the like formed of the same material as that for a magnetic disc. When the condensation or the like is detected by the condensation sensor, the magnetic disc is allowed to stand by in a state of remaining stopped rotating until it is not detected. Thus, damage to the magnetic disc and breakage of the head slider or the like due to their sticking can be previously prevented from occurring. Owing to the above construction, high humidity or condensation can be effectively detected and damage to a recording medium and breakage of the head slider or the like can be prevented satisfactorily.

摘要： A flying head slider is disclosed which can fly stably above the surface of a recording medium and thereby prevent deterioration of a reproduction signal output of the head. The flying head slider has a head for recording and reproducing information onto and from a recording medium and has an air bearing portion at an opposing portion thereof which opposes to the recording medium. The flying head slider is acted upon by buoyancy by air bearing caused by dynamic pressure between the air bearing portion and a surface of the recording medium. The flying head slider is disposed with respect to the recording medium such that, within a flying region of the flying head slider in a radial direction of the information recording medium between an inner circumference position and an outer circumference position of the surface of the recording medium, a flying pitch angle equal to or greater than 120 nullrad is formed between the air bearing portion and the surface of the recording medium.
