Tape drive with a tape roller assembly that includes a roller member and a stop mechanism
A tape drive includes a tape transport assembly, the tape transport assembly including a drive member, the drive member of the tape transport assembly configured to displace tape media in the tape drive; and a tape roller assembly, the tape roller assembly including a roller member, the roller member having one or more slanted grooves or protrusions formed in an outer surface of the roller member, the roller member configured to support and/or guide the tape media as the tape media is displaced by the tape transport assembly, the one or more slanted grooves or protrusions of the roller member configured to burnish and/or clean the tape media so as to prevent damage to a tape head, and the one or more slanted grooves or protrusions of the roller member being angled so as to prevent the tape media from sliding in an axial direction of the roller member.
Tape drive bearing temperature control
A determination is made whether read/write is enabled within the tape drive storage unit. In response to determining that read/write is enabled, a determination is made whether a temperature within the tape drive storage unit exceeds a threshold value. In response to determining that the temperature within the tape drive storage unit exceeds the threshold value, a determination is made of a direction of travel of a tape media within the tape drive storage unit. In response to determining that the direction of travel is a forward direction, a first cooling device is powered on. The first cooling device lowers the temperature of a first guide roller and the tape media coming off a first tape storage reel prior to the tape media passing by a read/write head within the tape drive storage unit.

Tape acclimation acceleration for environmental calibration
A method, according to one embodiment, includes cycling a shorter length of a tape, that is less than an entire length of the tape, a plurality of times to acclimate the shorter length of the tape. An acclimation change amount of the shorter length of the tape is determined. The acclimation change amount is based on a baseline servo band difference (SBD) measured before the cycling and a post cycling SBD measured after the cycling. The method further includes adjusting SBD values from a beginning of the tape (BOT) to an end of the tape (EOT) based on the determined acclimation change amount. A system according to another embodiment includes a processor, and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor. The logic is configured to cause the processor to perform operations of the foregoing method.

GUIDE ROLLER HAVING MAGNETS AND BUSHINGS TO STABILIZE A ROLLER BARREL FOR A TAPE MEDIUM
Provided are a tape guide roller and tape drive having a guide roller having magnets and bushings to stabilize a roller barrel for a tape medium. The tape guide roller has a roller barrel extending around a vertical axis. The tape medium passes across the roller barrel to guide the tape medium on a tape path. A plurality of magnets positioned with respect to the vertical axis provide an axial force to stabilize the tape guide roller axially.
Magnetic head
The present invention provides a magnetic head for erasing data on a magnetic tape, the magnetic head comprising a body having an elongate magnet mounted thereon, and a plurality of magnetisable portions in magnetisable communication with the magnet, the plurality of magnetisable portions being aligned with the elongate magnet and forming at least a portion of a substantially planar external surface of the magnetic head. The present invention further provides a method and system for erasing data on a magnetic tape using said magnetic head.
TAPE HEAD AND SYSTEM HAVING ASYMMETRICAL CONSTRUCTION
According to one embodiment, a computer-implemented method includes receiving a measurement of a first distance from a first edge to a sensor, receiving a predefined height of tenting of a magnetic recording tape above the sensor, and calculating a wrap angle to create the predefined height of tenting when the magnetic recording tape passes over the first edge in a direction of tape travel.
