摘要： A method is disclosed for controlling the write head of a magnetic disk storage device. The method includes sinking current from the first terminal of the write head and sourcing current to the second terminal of the write head substantially simultaneously with sinking current from the first terminal so that a first steady state voltage level appears on the first terminal of the write head and a second steady state voltage level appears on the second terminal thereof that are approximately at a midpoint between a high reference voltage level and a low reference voltage level. The common mode voltage of the write head is substantially constant over time.

摘要： Method and system of perpendicular magnetic recording and reproducing with ultra-high density for use in computer storage, audio, video recording euipment. Marks, as logical “1”-s are recorded at predeteremined distance from one another and their magnetic axes oriented in the opposite directions, as logical “0”-s are non-magnetized, forming pattern similar to chess-board order with the zero potential lines, eliminating crosstalk. Interaction “head-medium” is based on non-contact magnetic modulation, eliminating tribology problems. System may compose single or multi track medium, transporting linearly or rotating, with the immovable, quasi-immovable or scanning bi-polar or uni-polar magnetic heads, which have extremely small pointing conjugation area for interation with superminiature dimensions of magnetic fields of marks. System is realized by forming and recognizing the logical meaning of signals under checking of the strict general sequence different-directed alternation marks inside the tracks and in the neighboring tracks relatively of each other.

摘要： An apparatus (and method) is provided that reduces thermal interference in the read signal of a disk drive. A variable or programmable resistance is used to change the transfer function of a filter in the read channel of the disk drive to filter the read signal. The filter has a first transfer function (first cut-off frequency) related to the programmed resistance during normal operation of the disk drive (i.e. when thermal interference is not detected). When thermal interference is detected in the read signal, the resistance is programmed to another value resulting in the filter having a second transfer function (second cut-off frequency). The resistance element includes a transconductance amplifier whose transconductance is variable or programmable to different values resulting in different programmable transfer functions (or one of a multitude of cut-off frequencies) for the filter. In the preferred embodiment, detection of thermal interference increases the cut-off frequency of the filter thereby filtering, or reducing the effects of, the thermal interference in the read signal.

摘要： A head amplifier circuit supplies a writing current, having a direction in accordance with recording information, to a head for recording information on a recording medium. The head amplifier circuit includes a reference voltage generating portion for generating a reference voltage, a constant current generating portion for generating a constant current based on the reference voltage generated by the reference voltage generating portion, and a grounding portion. During one period of time, the constant current generating portion supplies the constant current to a first end of the head and the grounding portion grounds a second end of the head. During another period of time, the constant current generating portion supplies the constant current to the second end of the head and the grounding portion grounds the first end of the head.
