A disc drive includes a transducer having a separate element for writing
information and a separate element for reading information to and from
the disc. In a disc drive designated to read and write long sequential
records, the track misregistration budget is reduced to account for
previously written tracks not being encroached on one side. An initial
track is written. Subsequent tracks are written after a seek in one
direction. The subsequent track is written so that the initially written
track is overwritten to one side and leaves a track having a width
substantially equal to the width of the read element. Records can be
written into data bands of a selected number of tracks. A guard band is
left between groups of data bands so that data on tracks in subsequent
data bands are not overwritten.
