Abstract:
A read/write head for use in a direct access storage device (DASD), the read/write head comprising:a write element that receives a write signal and causes data to be recorded onto the surface of a recording disk in a write process; and a read element that transduces data recorded on the surface of the recording disk from servo tracks and data tracks, and generates a readback signal in a readback process; wherein the read and write elements are radially offset to each other such that they are aligned in the same servo track at the outside diameter (OD) data track and the same servo track is used for read and write operations at the OD, whereby the contribution of servo-writer TMR at the OD is minimize to zero for the readback process and total TMR at the OD is primarily a function of conventional read-write element error (WR) TMR and write-write error (WW) TMR, and wherein different servo tracks are used for the read and write elements at the disk inside diameter (ID), such that the total TMR at the ID is a function of both the WW TMR and WR TMR components, and the servo-writer TMR.
