Abstract :
The peak shift due to packing density and other effects in flexible disk drives is discussed. Some of the effects merely cause loss of high-frequency components and may be corrected by a suitably designed filter. The design requirements are qualitatively summarized. Comparison with and use with write precompensation is discussed.
