Method for recording digital data so as to avoid operational error on reproduction

摘要

A method for recording digital data on a tape in such a manner that the recorded data will not cause misoperations of the reproducing apparatus due to an excessive error rate. A flag in received data is monitored. When the flag indicates that a block of data contains more errors than can be corrected in the reproducing apparatus upon reproduction, the data block is either replaced by null data or a previously received data block having an acceptable error rate, the choice being in accordance with an input mode instruction.
