Abstract: Technologies are described herein for determining the linear storage density of data tracks on a recording media of a storage device while compensating for segments of the recording media with poor bit-error rates. The sectors of the data track are grouped into a plurality of segments and a bits-per-inch capability (“BPIC”) value is determined for each of the plurality of segments based on a target bit-error rate. The lowest segment BPIC value from amongst the plurality of segments is then determined as well as an average BPIC value for the entire data track. The final BPI value for the data track is determined based on the average BPIC value and the lowest segment BPIC value.
