摘要： A negative pressure air bearing slider including a first air bearing surface formed on the bottom of the slider body at the upstream position so as to extend in the lateral direction of the slider body, and a pair of second air bearing surfaces formed on the bottom of the slider body separately from the first air bearing surface at downstream positions spaced in the lateral direction so as to define an air stream passage therebetween. The second air bearing surfaces serve to generate positive pressures that are spaced apart at downstream positions where a transducer element is embedded in the slider body, so that the slider's stiffness to rolling action can be enhanced. The cooperation of the front and rear rails enables for the creation of a higher negative pressure.

摘要： A magnetic memory device comprises: a vertically magnetic recording medium; a probe formed of an electrically conductive as well as soft-magnetic material, a pointed end of the probe faces the magnetically recording medium across a gap; a magnetic flux detecting element for detecting a magnetic flux caught by the probe, where the magnetic flux is from a data recorded on the magnetically recording medium; a vertical controller for keeping the gap constant by the use of a tunnel current flowing via said gap into the probe while a voltage is applied across the gap; and a scan mechanism for scanning the probe along the magnetically recording medium. The magnetic memory device may further comprises an exciting coil for magnetizing the probe so as to write a data in the magnetically recording medium. The probe may be recessed from the scanning position when the probe is not in operation.

摘要： A servo system, for positioning a transducer of a rotatable storage apparatus over a servo tracks of a magnetic disc processes trains of positioning pulse signals. A reference voltage, changing with time, having a predetermined pattern, is generated and compared with a train of positioning pulse signals. The magnitude of the positioning signals, which varies with the displacement of the transducer from a guide path to be followed, the number of the positioning signals exceeding the reference voltage pattern is counted and an error signal for the servo system is determined as a function of the count and is fed back in a digital form.
