    • PROBLEM TO BE SOLVED: To provide a magnetic tape device for increasing the service life of a magnetic tape and properly and quickly releasing adsorption between the magnetic tape and a magnetic head only when they are firmly stuck to each other. SOLUTION: The magnetic tape device 1 is provided with: a magnetic head 2 which records and reproduces data to/from the magnetic tape 7, a drive means 6 which runs the magnetic tape in contact with the magnetic head in response to the recording and reproducing operation of the magnetic head, a release means 3 which releases the contact between the magnetic tape and the magnetic head, and a failure detection means which detects an abnormal operation of the magnetic tape. When the failure detection means detects an abnormal operation while the magnetic tape runs, the release means forcibly releases the contact between the magnetic tape and the magnetic head.

    • PROBLEM TO BE SOLVED: To provide a magnetic recording/reproducing device of a helical scan system capable of detecting the dew condensation of a rotary head drum with higher accuracy and surely preventing a magnetic tape T and the rotary head drum from being damaged. SOLUTION: The number of rotation of the rotary head drum 1 during tape loading operation is monitored. In such a state that the tape loading operation is performed to a position where the magnetic tape T is slightly brought into contact with the rotary head drum 1, when the number of rotation of the rotary head drum 1 becomes the prescribed value or less, it is discriminated as dew condensation, rotation of the rotary head drum 1 is stopped, while unloading operation in a tape loading mechanism is performed, also, discrimination of dew condensation is performed from a continuous falling property of variation of the number of rotation of the rotary head drum 1 and an updating rate of the maximum number of rotation during tape loading operation, such control is performed that rotation of the rotary head drum 1 is stopped during dew condensation while unloading operation by the tape unloading mechanism cannot be performed.
