Abstract
A disk-drive-compatible magnetic tape cartridge is provided with a tape guide for accurately positioning a magnetic tape in relation to a disk drive head. The tape guide includes a positioning section to be aligned with a rotation axis of a center core assembly when the center core assembly is chucked on a turntable of the disk drive. The tape guide also includes a guide section defining a tape run path across the disk drive head. The guide section is formed integrally with the section to be aligned with the center core assembly and so distanced from the latter as to accurately position the magnetic tape with respect to the disk drive head. Since the tape guide has the positioning section and guide section integrally, the distance therebetween can be maintained precisely constant. Therefore, tracking by the disk drive head becomes easier to allow high-density recording.
