Abstract :
In magnetic tape recording systems, dropouts occur occasionally in readback signals, due to defects on the tape surface. In this paper, we compensate the dropouts by selecting one of pre-calculated equalizers according to detected envelope. Timing recovery is held from updating during dropouts.
