摘要：A hard disk drive or other disk-based storage device comprises a storage disk, aread/write head configured to read data from and write data to the disk, and control

circuitry coupled to or otherwise associated with the read/write head. The controlcircuitry comprises a write driver configured to generate a write signal for data to bewritten to the storage disk, and a multiple-slope transition controller associated with thewrite driver and configured to control a data transition in the write signal such that thedata transition comprises at least two different segments each having a different slope,with the transition controller comprising separate slope control mechanisms for each ofthe segments. By way of example, the data transition may comprise a dual-slopetransition having first and second segments arranged sequentially between a start pointand an end point of the data transition.
