1. A storage device, comprising:

  • a storage medium configured to store data using interlaced magnetic recording (IMR) having at least two different track densities (kilotracks per inch (ktpi));

    a power source configured to heat the storage medium; and

    a storage device controller configured to determine different linear densities (kilobits per inch (kbpij)) for tracks j with different track densities (ktpij), the determination based on satisfaction of a bit error rate (BER) threshold.
