Abstract
The invention relates generally to media carrying symbols representing digital information, the recovery from media of symbols representing digital information and the establishment of the digital information represented by such symbols. While the present invention has many applications, it is more particularly described in connection with preferred embodiments in which the symbols are recovered from and carried by tape- and disk-based storage media in which the symbols are arranged in spiral, concentric, parallel or linear tracks.
