Write current pulse driver and method of producing write pulse

A write current pulse driver and a method of producing write pulse are provided. The write current pulse driver includes a parameter storage, storing a set of parameters specifying characteristics of a write current pulse, and driver circuitry configured to generate the write current pulse on an output node, the write current pulse having a leading edge, a trailing edge and an intermediate segment between the leading edge and the trailing edge, wherein the driver circuitry includes pulse shaping circuits that set shape characteristics of at least one of an amplitude, a duration or a slope of one of three parts, which are the leading edge, the trailing edge and the intermediate segment, of the write current pulse using the set of parameters.
