Abstract
A data storage magnetic tape uses a volume control region (VCR) that contains all of the control information for the tape. There is a large span of blank tape after the VCR region before the actual data storage region of the tape. When a tape drive spools the tape between the VCR and data storage region, the tape motion is continued past the VCR region, after the VCR region is updated, into the region of tape where there is no data of any kind. Just before reaching the data storage region, the motion of the tape is reversed and the tape is rewound into the cartridge. The portion of the tape that experiences the motion reversal is prone to be thrown such that it protrudes from the other layers of uniformly layered tape. Even if these thrown wraps are damaged, this portion of the tape has no stored data, which increases the overall reliability of the information stored on the tape.
