ABSTRACT:
A recording tape cartridge is formed by joining together respective peripheral walls of an upper case and a lower case, and an label area is disposed at a rear wall of the upper case. An operational hole, for switching between a mode in which recording onto the recording tape is possible and a mode in which recording onto the recording tape is not possible, and an identification opening are disposed on a rear wall of the lower case. An operational portion and an identification portion of a mistaken erasure prevention plug are respectively exposed at the rear wall of the lower case. The identification opening opens downward and rearward with respect to the case. By operating the operational portion, the identification portion of the plug moves and the opening is opened and closed. By distinguishing between opened and closed states of the opening, the recordable and non-recordable modes are identified.
