Abstract: In order to take into account leakage resistances occurring in the case of information contacts (3a to 3n), it is proposed to pass the signal which is formed by an information contact (3a to 3n), together with a reference signal, to a comparison circuit (7). The output of the comparison circuit (7) then carries a signal which corresponds to the switching state of the information contact (3a to 3n). The signals of a plurality of information contacts (3a to 3n) are preferably passed to a multiplexer circuit (15, 17) whose output signal is passed to the comparison circuit (7). In a further refinement, the output signal of the comparison circuit (7) is passed via a potential-isolating element (21) to a control and processing device (23) having a processor. <IMAGE>

Abstract: In a clock recovery circuit, an asynchronous oscillator generates a first clock pulse at a frequency n times the frequency of a baseband signal. A sampler samples the baseband signal in response to the first clock pulses. A flip-flop holds and delivers the sampled signal in response to a second clock pulse supplied from a voltage-controlled oscillator. The time difference between the first clock pulse and the second clock pulse is detected and a set of tap-gain values is selected according to the time difference. The sample delivered from the flip-flop is successively delayed by a tapped delay line to produce tap signals which are respectively weighted with the selected tap-gain values. The weighted samples are summed to estimate an intermediate sample. A clock phase error of the estimated sample with respect to the clock timing of the transmitted signal is determined for controlling the VCO.

Abstract: This patent discloses a method of making a magnetic recording head slider having reduced friction and stiction and greatly improved contact start stop performance in a hard disk drive. It is found that conventional diamond particle abrasives used for machining, lapping and polishing for fabrication of sliders leave considerable surface and subsurface damage on the air bearing surface. The damage is microscopic and consists of mechanically weakened areas which can become dislodged and entrapped between the slider and the disk surface. The dislodged particles act as an abrasive and increase the friction between the slider and the disk, and lead to accelerated wear of the disk surface. In this invention, the mechanically weakened areas on the air bearing surface are selectively removed by a mechanical surface treatment process using particle abrasives other than diamond. The resulting slider surface has a high degree of mechanical integrity even when subjected to prolonged repeat impact motion against the disk surface in contact start stop operation. Consequently, the interface between the air bearing and disk surfaces is free of hard debris and therefore the friction at the interface can be drastically reduced from that of the untreated slider surface. The proposed surface treatment method also provides an additional advantage of further reducing head/media stiction through creation of micro-texture on the slider surface which results from mechanical treatment of the slider surface.
