Abstract
The present invention provides a data cartridge having a cartridge case (1) capable of containing either of two kinds of magnetic tapes differing from each other in width. The data cartridge is provided with a pair of guide rollers (8) for guiding a driving belt ((9) for driving a magnetic tape (5). Each guide roller (8) has a crowned working surface (8a) having a maximum portion having a maximum diameter. The maximum portion is dislocated from a position corresponding to the middle between the opposite ends of the guide roller (8) toward one of the opposite ends by a specific distance. Each guide roller (8) is set in a position in which the maximum portion is below the position corresponding to the middle between the opposite ends when the data cartridge is provided with a first magnetic tape (1/4 in. magnetic tape) or in a position in which the maximum portion is above the position corresponding to the middle between the opposite ends when the data cartridge is provided with a second magnetic tape (8 mm magnetic tape) having a width greater than that of the first magnetic tape.
