Extension of media noise modulation theory (square-wave recording)
1, Pulse shape modulation (PSM). i.e. pulse-width- and pulse-amplitude modulation (PWM and PAM) associated with transition-width fluctuations; 2. Pulse position modulation (PPM) or jitter caused by fluctuations of transition center. 3. At high densities, large zigzags can percolate into one another....

Zusammenfassung: | 1, Pulse shape modulation (PSM). i.e. pulse-width- and pulse-amplitude modulation (PWM and PAM) associated with transition-width fluctuations; 2. Pulse position modulation (PPM) or jitter caused by fluctuations of transition center. 3. At high densities, large zigzags can percolate into one another. and two adjacent transitions can disappear in some parts across the hack. |
