Abstract

A Pegasus-type data cartridge which reduces the drive speed and rotational load on a pair of left and right corner rollers and stabilizes the tape tension and tape drive force by employing a pair of left and right corner rollers whose outer diameters are 4.5 times the inner diameters thereof, such that even when the tape drive speed is high, an increase in the characteristic values of the tape tension and the tape drive force is reduced. Also, the length of the small width section of the cartridge in the insertion/extraction direction of the cartridge insertion slot of a recording/playback device is formed longer than the depth to which the small width section is inserted into the cartridge insertion slot, and the connecting surfaces connecting the left and right side surfaces of the small width section and the left and right side surfaces of the large width section are formed in a substantially tapering shape which widens in the extraction direction away from the cartridge insertion slot, such that when the small width section of the cartridge is inserted into the cartridge insertion slot, a space large enough for the operator to insert his/her finger therebetween is formed between one of the connecting surfaces and the eject button of the front panel of the recording/playback device.
