PROBLEM TO BE SOLVED: To provide a device for verifying the recording failure of a servo pattern which is made to the reference when a data track on a tape used for a recording/reproducing device is traced by a head. SOLUTION: The servo pattern 12 is formed on the tape 2 as the pattern having the determined dimension. The tape 2 is run by a tape driving device 1. The servo pattern 12 recorded on the tape 2 is reproduced by a reproduction head 6. The reproduction head 6 is moved in the breadthwise direction of the tape 2 by a head moving means 9. By the reproduction head 6, the reproduction is made for every one part of the recording width W of the servo pattern 12 while changing the height. A signal of the reproduction head 6 is detected by a detection means 7, and the recording failure is verified by a verifying means 8 based on the signal of the detection means 7. At this time, the position of the reproduction head is also detected by the verifying means 8 while making the longitudinal direction of the tape 2 to an X-axis, the breadthwise direction to a Y-axis. By a recording means 11, the positional information with the X-axis or Y-axis is also recorded in relation to the verifying result.
