摘要:
A tape reel assembly for use in a tape drive system for winding and unwinding storage tape is described. The tape reel assembly has a hub including a cylindrical core, an annular wall, and a web connecting the annular wall to the cylindrical core. The annular wall is co-axially disposed exterior to and separated from the cylindrical core and defines a tape-winding surface. The web extends between the annular wall and the cylindrical core and defines a first surface and a second surface. In this regard, at least one of the first surface and the second surface is shaped to approximate a sinusoid in radial cross-section.

A data storage tape cartridge is disclosed. The data storage tape cartridge includes a housing, a reel assembly including a hub rotatably disposed within the housing, a storage tape wound onto the tape reel assembly, and a leader attached to a leading end of the storage tape. In this regard, the storage tape includes a primary tape portion extending from the hub to a first end and a transition tape coupled to the first end of the primary tape portion and extending to a leading end, wherein the transition tape is thicker than the primary tape portion.

A data storage device is disclosed. The data storage device includes a continuous band, and a memory device assembly disposes within the continuous band. The continuous band defines an internal housing recess formed by opposing sides extending between first and second major surfaces, and an access window formed in one of the first and second major surfaces and communicating with the internal housing recess. In this regard, the memory device assembly is disposed in the internal housing recess, and a flexing of the continuous band exposes a data/power port of the memory device assembly through the access window.

A flash memory device is disclosed. The flash memory device includes a housing enclosing a memory board, a serial port extending from the housing and electrically coupled to the memory board, and a swivel cap rotatably coupled and removably attached to the housing. In this regard, the swivel cap is rotatable between a closed position covering the serial port and an open position exposing the serial port, and the swivel cap is rotatable to at least one removal position enabling a separation of the swivel cap from the housing.

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.
