An apparatus and method for increasing the data storage capacity of a data storage
device 100 having media surfaces 23. One or more of a linear density
of data, a track density of data, or an error code level of data, is selected for
a portion 35 of a media surface 23. Data is recorded on the portion
35 of the media surface 23 at the selected linear density, track
density, or error code level. Thereafter, the recorded data is read and an error
rate of the recorded data is derived, directly or indirectly. The derived error
rate is compared to an acceptable error rate, and if the derived error rate is
greater than the acceptable error rate, the previous steps are repeated for another
linear density, track density, or error code level, until the derived error rate
is less than or equal to the acceptable error rate, to provide a recordable linear
density, track density, or error code level of data for the media surface 23.
