ABSTRACT:
A method and disc drive in which tracks and data rates are designated is provided. Under the invention, the write width of a transducer head is determined. A tracks per inch value is adjusted based on the write width, and a data transfer rate is adjusted based on the adjusted tracks per inch value. In particular, the data transfer rate is adjusted such that the adjusted tracks per inch value and the adjusted data transfer rate provide a capacity for the head that is equal to a nominal capacity.
