ABSTRACT:
A data reproduction method and a circuit therefor for use in a digital magnetic recording/reproduction apparatus. The circuit includes a reproduction amplifier, a reproduction equalizer, a data detector, a reproduced clock recovery portion, a data/clock synchronizer, and a glitch error removal portion. The method and apparatus operates to remove a glitch error which may occur when the digital data recorded on the recording medium is recovered. The data from which the glitch error has been removed is synchronized with a reproduced clock. Removal of the glitch error prevents misoperation of the devices which perform subsequent operations, and improves the bit error ratio of the overall reproduction system.
