Helical-scan video tape recorder having a tape-loosening mechanism

摘要

An apparatus for scanning a magnetic video tape includes a drum and a rotatable magnetic head. A freely rotatable roller and a loosening mechanism are positioned on opposite sides of the tape. When the tape stops, the loosening mechanism is driven toward the roller and thus engages the tape between the loosening mechanism and the roller. Rotation of the loosening mechanism then loosens the tape.
