Abstract:
1. A method of voltage biasing one or more elements of a tape head assembly of a tape drive to limit tape stain accumulation on the tape head assembly, comprising: obtaining a first set of one or more environmental variables of a tape drive that collectively make up a first environment of the tape drive; determining, based on the first environment, a first set of one or more voltage biases to be applied to a first set of one or more elements of a tape head assembly of the tape drive to limit the accumulation of tape stain on the tape head assembly during movement of magnetic tape relative to the tape head assembly in the first environment; applying the determined first set of one or more voltage biases to the first set of one or more elements of the tape head assembly; obtaining a second set of one or more environmental variables of a tape drive that collectively make up a second environment of the tape drive; determining, based on the second environment, a second set of one or more voltage biases to be applied to a second set of one or more elements of the tape head assembly to limit the accumulation of tape stain on the tape head assembly during movement of the magnetic tape relative to the tape head assembly in the second environment; and applying the determined second set of one or more voltage biases to the second set of one or more elements of the tape head assembly, wherein the first and second sets of one or more elements of the tape head assembly are different.
