Abstract
According to one embodiment, a method for processing data includes determining whether a PES is invalid while reading data from a magnetic medium using at least one data channel, determining whether a PES value is above a first predetermined threshold when the PES is valid, injecting error bits into a data stream in place of corresponding bits of decoded data when the PES is invalid and/or the PES value is above the first predetermined threshold, decoding the data using a run-length limited (RLL) decoder to produce the decoded data based on the data from the magnetic medium, and outputting the data stream. Other methods, systems, and tape drives for processing data using error injection are described in more embodiments.
