Patent attributes
A tape supply-side hub, a tape take-up-side hub and a magnetic tape wound onto the tape supply-side hub are included inside a mainframe case. A leader tape fixed onto the tape take-up-side hub and one end of the magnetic tape are connected via a splicing tape. The other end of the magnetic tape is wound onto the tape supply-side hub, and the magnetic tape and the tape supply-side hub are directly connected with adhesive agents. A wound tape layer wounded onto the tape supply-side hub in the fully wound state is composed of a non-recording layer on the winding leader side composed of a specified amount of the wound tape layer and a recording layer continuing to the non-recording layer. The feeding limit position of the magnetic tape in the tape supply-side hub is set to be in the vicinity of a boundary between the non-recording layer and the recording layer.
