摘要:
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.

The invention is directed to a magnetic field sensing device (FSD) capable of visually indicating exposure to a magnetic field with a strength that exceeds a threshold value. The magnetic FSD comprises a magnetic layer magnetized to define a pattern. The threshold value is approximately equal to a coercivity of the magnetic layer of the FSD, which is at least approximately 3000 Oersteds. The pattern becomes visible when a finely divided magnetic material is applied over the magnetic layer. Then, when the FSD is exposed to a magnetic field with a strength that exceeds the threshold, the pattern visibly alters (e.g., typically disappears altogether). Accordingly, upon re-application of the finely divided magnetic material, the alteration of the pattern is evidence of successful degaussing.

The invention is directed to a magnetic field sensing device (FSD) capable of visually indicating exposure to a magnetic field with a strength that exceeds a threshold value. The magnetic FSD comprises a magnetic layer magnetized in a pattern and a material positioned adjacent the magnetic layer to render the pattern visible. When the FSD is exposed to a magnetic field with a strength that exceeds the threshold, the pattern visibly alters. The threshold value is approximately equal to a coercivity of the magnetic layer of the FSD, which is at least approximately 3000 Oersteds.

A tape reel assembly for a tape drive system component, such as a data storage tape cartridge, is described that includes a hub. The hub defines an inner surface and a tape winding surface, and at least a portion of the hub is made of plastic. The tape winding surface has an effective radial modulus of greater than 0.3 million pounds-per-square-inch.

A tape reel assembly for a data storage tape cartridge is described. The tape reel assembly has a hub. The hub includes a cylindrical core, an annular arm, and a web. The cylindrical core defines a drive side and a top side. The annular arm is co-axially disposed exterior to and separated from the cylindrical core. Additionally, the annular arm defines a tape winding surface bisected by a center line into a top half opposite the drive side and a bottom half adjacent the drive side. The web extends from the top side of the core, and a web center connects to the annular arm at a point in the top half.
