Abstract

The system transfer function of magneto-optic data storage systems can be significantly improved by superresolution. Superresolution is achieved using optical and electronic filters. In our experiments the relative high frequency contrast improved from 10% to 75% after application of a combined optical and electronic filter. The carrier-to-noise ratio was slightly degraded at low frequencies, but was improved by 2dB to 3dB at high frequencies. Measurements indicate that the combined system improves jitter by a factor of three at high frequencies.
