ABSTRACT:
A novel tape testing apparatus of the type which senses errors, stops the tape, and causes the error to be moved to an error-correction or an error-inspection station. The apparatus of the invention is characterized by means to rapidly try to remove the error by additional passes through an error removal station and then, if necessary bring the error-bearing portion of the tape precisely under an inspection station by a precise distance-metering process.
