摘要： An apparatus, according to one embodiment, includes a module having a tape bearing surface, an array of magnetic transducers, and a channel in the tape bearing surface. The channel has a longitudinal axis oriented about parallel to a longitudinal axis of the array of magnetic transducers for inducing tenting of a moving magnetic recording tape above the array of magnetic transducers. Moreover, the channel has a shape with a middle section of similar recession therealong between straight opposite ends.

摘要： A method of operating a magnetic tape within a tape drive. The tape drive comprises a tape head, which shows a tape-bearing surface meant to face a front side of a magnetic tape, in operation. The tape-bearing surface comprises a transducer area. This area includes at least one transducer, which is a read or write element configured to read or write to the magnetic tape, respectively. The method may include driving the tape (along a longitudinal direction of circulation thereof above the tape-bearing surface) and concomitantly ejecting a gas flow toward the transducer area. The gas flow ejected impinges on the back side of the driven tape (e.g., opposite to the front side of the tape), so as to locally urge the front side of the tape against the transducer area and thereby read or write to the tape via said at least one transducer.

摘要： A slider resistant to lubricant accumulation. The slider resistant to lubricant accumulation includes a positive-air-pressure portion of the slider configured to levitate the slider above a magnetic-recording disk and a negative-air-pressure portion of the slider configured to bring the slider into proximity with the magnetic-recording disk at a fly height sufficient for writing data to and reading data from the magnetic-recording disk. The slider resistant to lubricant accumulation also includes a lubricant-accumulation barrier disposed in proximity to a trailing edge of the slider. The lubricant-accumulation barrier is configured to reduce lubricant accumulation on the slider.

摘要： A head gimbal assembly (HGA) has an improved interconnection between a head slider and a suspension of the HGA. The interconnection is achieved by using a reverse surface of an air bearing surface of the head slider as bonding surface to provide more space for arranging more slider electrical bonding pads thereon. The head slider is mechanically and electrically connected to the suspension at the bonding surface to have good performance on shocking conditions. The suspension further has an attitude control layer located between the head slider and the suspension. The attitude control layer serves as a datum plate for the head slider lying thereon and supporting the head slider so as to ensure the head slider a good attitude and reduce variation of slider flying height. The present invention also discloses a magnetic disk drive with the improved HGA and a fabricating method for the HGA.
