Abstract

A method for writing data to a magnetic data storage medium includes detecting whether the duration, before occurrence of a data transition, of data to be written exceeds a predetermined threshold, and, when the duration, before the occurrence of the data transition, of the data to be written exceeds the predetermined threshold, writing the data by applying an initial pulse and then maintaining a steady-state write current for a defined interval, and when the duration, before the occurrence of the data transition, of the data to be written is at most equal to the predetermined threshold, writing the data by applying the initial pulse without applying a steady-state write current before the data transition. The predetermined threshold may be determined by size of a magnetic bubble formed when writing a single bit to the magnetic data storage medium. A subsequent pulse may be applied following the defined interval.
