Abstract: A storage system for storing information on a magnetic media is embodied within a conversion device. The system is operable to store data within a bit cell by receiving data from a controller board (14), which data is generated by a Central Processing Unit (CPU) (52). This data is convened from an ordinary Modified Frequency Modulation (MFM) format received on a bus (32) and then convened to a Super High Density (SHD) data format. In the SHD format, a counter is provided for counting down from an initial starting time corresponding to a reference pulse (102) to an end count value corresponding to the value of a data word. The time between the reference pulse and the end of count value constitutes the length of time from the beginning of the bit cell to the position in the bit cell at which a data pulse is recorded. During a decode operation, i.e.
