Abstract
A system and process for constructing a magnetic storage drive capable of single pass self-servowriting. A plurality of heads are sorted, or 'binned,' into classifications based on at least an approximate magnetic width of each head. Only heads from a single classification are installed in a particular disk drive system. A track overlap value is calculated, preferably empirically, for the approximate magnetic widths of typical heads in the single classification. The overlap value is used to determine a track spacing utilized during a self-servowriting process.
