Magnetaufzeichnungs- und Wiedergabemethode und Gerät
摘要
A digital signal to be recorded is converted into a digital signal having a suppressed low-frequency spectrum and having a shortest recording wavelength greater than half an original shortest recording wavelength, and the converted digital signal is recorded on a magnetic recording medium in which a plurality of metal evaporated films having different crystal-growth directions are laminated. The digital signal is reproduced from the magnetic recording medium in which the plurality of metal evaporated films having different crystal-growth directions are laminated. Waveform equalization is performed on the reproduced digital signal, and integration detection is performed on the waveform-equalized digital signal, thereby restoring an original digital signal. <IMAGE>
