Abstract: METHOD AND APPARATUS USING MULTIPLE CODES TO INCREASE STORAGE CAPACITY To increase storage capacity of a disk storage device, the recording surface of the device is partitioned into a plurality of concentric recording bands, data to be recorded on respective bands are encoded using different run-length-limited codes with the code rate of each band being higher than the adjacent inner band.

Abstract: SA9-90-072 INDUCTIVE CURRENT SWITCHING SYSTEM AND METHOD of the Disclosure An inductor is connected in parallel with a capacitor. A first and a second current source provide current to the inductor in opposite directions. Rapid current switching in the inductor is achieved by allowing the inductor and capacitor to resonate in a time period between the application of current from the first and second current source.
