BACKGROUND
The invention relates to a disk drive recording apparatus
and method for improving the seek time by utilizing two
magnetic heads on a single side of the disk. The disk
recording medium is divided into three equally spaced
intervals and the heads are spaced apart by a distance equal
to one of the intervals as shown in figure 3. In the center
interval, between N/3 and 2N/3, either head can read/write
data. According to the invention, in the center interval the
head closest the target track is selected to read/write data.
