Improvement in a digital computer system, processes of correct data temporizacao and effects on change of speed and apparatus for correcting changes in temporizacao

摘要

A method of correcting bit timing errors introduced by the storage of data in and/or the recall of stored data from a data storage device, comprising considering the timing errors so introduced as frequency-modulations to a stream of data to be stored, and re-modulating an output stream of data from the storage device as a function of the actual or expected frequency-modulations so introduced, thereby reducing or removing the bit timing errors. The invention also relates to apparatus for carrying out the method.
