Data storage tape cartridge with wear-resistant brake assembly

A tape drive system comprising:

• a tape drive including:
• a motor,
• a drive chuck rotatably driven by the motor, the drive chuck including:
• an engagement hub,
• a spindle extending axially from the engagement hub, the spindle terminating in a tip;
• a data storage tape cartridge comprising:
• a housing defining an enclosure, the enclosure being accessible through an opening in the housing,
• at least one tape reel rotatably disposed within the enclosure, the tape reel defining a central bore axially aligned with the opening,
• a storage tape maintained by the tape reel,
• a brake body slidably disposed within the central bore, the brake body configured to selectively rigidly connect the tape reel to the housing in a locked position and including a button terminating in a leading end, the brake body being positioned such that the leading end is accessible via the central bore,
• a spring biasing the brake body to the locked position;
• and
• an engagement assembly established between the tip and the leading end, the engagement assembly comprising:
• a rounded surface,
• a concave surface configured to selectively receive the rounded surface;
• wherein during use, the tape drive system is configured such that the engagement hub engages the tape reel and the rounded surface is received by the concave surface to direct the brake body out of the locked position.

A method of operating a tape drive system, the method comprising:

• providing a tape drive system including a tape drive, a data storage tape cartridge and an engagement assembly, wherein the tape drive includes a frame and a drive chuck having an engagement hub and a spindle terminating in a tip, and further wherein the data storage tape cartridge includes a housing, at least one tape reel rotatably disposed within the housing, a storage tape maintained by the tape reel and a brake body configured to selectively connect the tape reel to the housing in a locked position, the brake body including a button terminating in a leading end, and further wherein the engagement assembly is established between the tip of the spindle and the leading end of the brake body and includes a rounded surface and a concave surface configured to selectively receive the rounded surface;
• inserting the data storage tape cartridge into the frame;
• directing the spindle toward the brake body such that the rounded surface contacts the concave surface;
• guiding the brake body from the locked position with further movement of the spindle;
• engaging the tape reel with the engagement hub;
• rotating the drive chuck to rotate the tape reel, wherein the spindle rotates with rotation of the drive chuck, whereas the brake body remains stationary;
• ceasing rotation of the drive chuck;
• and
• retracting the drive chuck such that the rounded surface disengages the concave surface.

A brake body for use with a data storage tape cartridge for selectively rigidly connecting a tape reel to a cartridge housing in a locked position, the brake body comprising:

• a stem forming a slot sized to slidably receive a portion of housing;
• a reel engagement section configured to selectively engage a portion of a tape reel in a locked position;
• and
• a button positioned opposite the stem, the button terminating in a leading end forming a concave surface configured to selectively receive a rounded surface associated with a tape drive.

A data storage tape cartridge comprising:

• a housing including:
• a first housing section including a connector,
• a second housing section forming an opening opposite the connector, the housing sections combining to define an enclosure;
• at least one tape reel rotatably disposed within the enclosure, the tape reel defining a central bore;
• a storage tape maintained by the tape reel;
• a brake body disposed within the central bore of the tape reel, the brake body including:
• a stem configured to slidably receive the connector,
• a reel engagement section configured to selectively engage a portion of the tape reel in a locked position,
• a button positioned opposite the stem and terminating in a leading end, the leading end forming a rounded surface configured to be selectively received by a concave surface associated with a tape drive;
• and
• a spring biasing the brake body to the locked position;
• wherein the rounded surface is accessible through the opening in the second housing section and the central bore in the tape reel.
