Recording tape cartridge and drive device thereof

摘要

A recording tape cartridge which can be assuredly positioned in a drive device. A positioning cover bridges across and parallel to a mounting portion of a bucket of the drive device. Stoppers are provided at corner portions of the positioning cover that are positioned at a deeper side of the bucket. Angled surfaces, which are surface-contactable with the stoppers, are provided at a magnetic tape cartridge. The magnetic tape cartridge can be positioned in horizontal directions in the drive device by surface-contacting the angled surfaces with the stoppers. Consequently, reference holes for positioning the magnetic tape cartridge in horizontal directions in the bucket are not required.
