Abstract

Described herein is a method to dynamically adjust for tape speed variations by updating data bit decision rules based on the most recent data bits read. This method decreases the probability of making an error when deciding whether a data bit read from a cassette tape is a "0" or a "1" by dynamically adjusting the decision rule based on the duration of previously decoded data bits.
