The present invention provides a VCR deck inspection system having a failure prevention jig during deck capstan M / T and drum M / T drive inspection of the VCR deck.;The VCR deck inspection system with deck capstan M / T and drum M / T drive checker jigs on its VCR decks provides the ability to deck drive power or data and GND input lines to drive drives such as drums or capstans on the VCR deck. A deck pallet 10 unitized by a 50-pin connector of the pallet; A measuring unit 30 which is a measuring means for displaying the test result on the screen; A deck mounting jig unit 20 that acts as an input to the deck pallet unit for power, GND, and data signals for VCR deck inspection, and generates an output waveform as an input of the measurement unit 30; Drum M / T generated during the inspection of the VCR deck and deck capstan M / T and drum M / T failure preventing jig 40, which is a failure prevention means of the capstan M / T; It is characterized in that it comprises a bus connector 52 connecting the deck pallet 10 and the deck failure prevention jig 40.;As a result, when the deck mounting jig 20 and the deck pallet 10 are coupled to each other, the potential difference between the open and the electrostatic discharge of the ground and the ground connection between the jig and the deck by the sequential connection of the deck failure preventing jig 40. This eliminates the reverse voltage applied by the drum and prevents the deck M / T and capstan M / T defects.
