ABSTRACT:
The invention is directed to techniques to substantially reduce or eliminate detachment of data storage tape from data storage cartridges. A data storage cartridge may include a housing enclosing a spool with data storage tape spooled on the spool. A region of the data storage tape extends from the spool to an opening in the housing. An end of the data storage tape is held at the opening to allow tape drives to grasp the data storage tape and retrieve data stored on the data storage tape. When dropped, the data storage cartridge experiences impact loads. The techniques described herein rotate the spool to generate slack such that the region of data storage tape comprises substantially no tension. In this way, the techniques prevent detachment of the data storage tape from the opening due to the impact loads.
