摘要： Methods and apparatus are provided related to magnetic recording tape. Respective voltage sources are coupled to respective magnetic head components of a tape recording apparatus. Circuitry controls each voltage source independently in accordance with identity information for a magnetic tape, relative humidity within the tape recording apparatus, or other factors. Chemical migration from the tape, and/or plating or erosion of elements of the tape recording apparatus are substantially reduced or eliminated according to the present teachings.

摘要： A data recording system includes media such as a magnetic disk or tape, a read/write head assembly, and a circuit that provides a write signal having edge placement equalization. The circuit responds to a binary serial data signal such as a run length limited signal of the type (1,x) and provides a write signal having data transitions corresponding to one of the two binary data values, the absence of a transition corresponding to the other data value. In addition, the write signal is provided with a pair of equalization transitions during periods of no data transitions. A first data transition is shifted away from the last provided equalization transition by a predetermined offset. A second data transition, provided immediately after the first data transition, may be shifted toward the last provided equalization transition. Timing of the data transitions is derived from a clock used to provide the equalization transitions.
