ABSTRACT:
Data deskewing apparatus includes two, byte organized random access memories for storing, aligning and then reading out channels of data which were originally skewed when read in from a multitrack magnetic recorder system. While write-in operations on skewed data are taking place in one of the random access memories (RAM), read-out operations on skew-corrected data, which had been written in on the previous cycle, are taking place in the other RAM. On the completion of a write in/read out cycle, the roles of the RAM's are interchanged, and the process repeated.
