Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a noise elimination device easily improving noise resistance and a digital data storage device containing it. SOLUTION: A noise elimination means 8 is provided between a write data input terminal 6 of an FDD 1 and a write circuit 7. The noise elimination means 8 is constituted of a D type flip-flop 9 and a counter 10. The trigger input terminal T of the D type flip-flop 9 is connected to the write data input terminal 6. The positive phase output terminal Q of the D type flip-flop 9 is connected to the reset terminal R of the counter 10. The output terminal of the counter 10 is connected to the reset terminal R of the D type flip-flop 9. The negative phase output terminal Q of the D type flip-flop 9 is connected to the write circuit 7. The measurement time width of the counter 10 is set shorter than the minimum period of the write data.
