Abstract:
A system for reducing electro magnetic pulses in a drive after a write operation comprising:a write element;write circuitry adapted for applying a current to said write element to cause magnetic domains of-said write element to be in a high energy state to perform a write operation on a magnetic media of a disk; andstep circuitry connected to said write circuitry operable to reduce said current applied to said write element to an intermediate level for a predetermined period of time before stopping the flow of said current to said write element in order to reduce said magnetic domains of said write element from the high energy state to an intermediate energy state then to a low energy state after said predetermined period of time in order to prevent said write element from creating pulses as said write element goes from said high energy state to said low energy state, wherein said predetermined period of time is on the order of 1 microsecond.
