Abstract
Various illustrative aspects are directed to a data storage device comprising a disk and a read/write head configured to read data from and write data to the disk. The read/write head comprises a write pole tip and a transducer configured near the write pole tip. One or more processing devices are mounted on or near the read/write head and generate an AC current that is applied to the transducer to cause the transducer to generate a high frequency auxiliary field that is applied to the disk. The one or more processing devices may be an RF source IC mounted on or near a slider on which the read/write head is integrated or mounted.
