Disk drive compatible tape cartridge with device for positioning the tape relative to the disk drive

A magnetic tape cartridge suitable for transferring data between a magnetic tape and a disk drive head in a disk drive which is designed for driving a magnetic disk, comprising:

• a cartridge casing acceptable in a disk drive and defining therein a tape run path across a disk drive for transferring data between a magnetic tape and said disk drive for recording and reproducing a tape track formed on said magnetic tape;
• a tape drive mechanism for driving said magnetic tape along said tape run path, said tape driving mechanism being designed to selectively drive said magnetic tape both in forward and reverse directions;
• a center core assembly received within said cartridge casing and exposed therefrom to be chucked by a disk driving mechanism of said disk drive, said center core assembly including a chucking means active for establishing chucking engagement between said center core assembly and said disk driving mechanism to said tape drive mechanism, and
• a tape positioning means housed within said cartridge casing for positioning said magnetic tape in a predetermined position with respect to said disk drive head, said tape positioning means including a positioning section and tape guide section, said sections being integrally formed wherein alignment of the positioning section with the rotation axis of the said center core assembly results in highly accurate tracking of said disk drive head with respect to said magnetic tape.
