ABSTRACT:
An information transfer system having a high information transfer rate of the type utilizing a storage medium and associated transducer means, the combination including a movable storage medium having an information path formed thereon and having an information storage capacity. Transducer means is adapted to sequentially scan the information stored along said information path and respond to information stored along said path. The combination further includes a first information reproduction channel including a first information track formed along said path on said medium and a first transducer responsive to said first track, said first channel having a rate limited information transfer capacity of C1 and a second information reproduction channel including a second information track formed along said path on said medium and a second transducer responsive to said second track, said second channel having a rate limited information transfer capacity of C2. Means is provided for combining the output of said first and second channels to provide an information transfer capacity of the sum of C1 and C2.
