Abstract
An error repairing method and apparatus for a magnetic bubble memory for restoring stored binary data to its original form are described. The method and apparatus are employed to compensate for random error in bubble memories resulting from slipped or disappeared bubbles. The data is coded with an error correcting code, such as a Hamming or Fire code, before storage. The stored, coded data is periodically read from memory and errors are detected and corrected. The corrected, coded data is rewritten into memory. In one embodiment the frequency of the repair cycles is a function of the rate at which errors are detected.
