Claim Text:
1. A method of classifying bit errors in run length limited data transmitted over a channel, comprising: encoding a test pattern using a run length limited line encoding to produce a first encoded block of data, the first encoded block of data having no more than a first maximum number of consecutive bits having the same value, the first encoded block of data having a first run of the first maximum number of consecutive bits having the same value; changing at least one bit in the first encoded block of data to produce a second encoded block of data, the second encoded block of data having a second maximum number of consecutive bits having the same value, the second maximum number of consecutive bits greater than the first maximum number of bits, the second encoded block of data having a second run of the second maximum number of consecutive number of bits having the same value; sending, to a receiver, the second encoded block of data via the channel, the channel coupled to said receiver; receiving, using said receiver, a received block of data corresponding to the sent second encoded block of data; comparing a plurality of bits in the received block of data that are subsequent to the second run to an expected plurality of bits; and, classifying a type of bit error based on a mismatch between the expected plurality of bits and the plurality of bits that are subsequent to the second run in the received block of data.
