Abstract
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 an absolute value of a channel offset exceeds a threshold value. In response to determining that the absolute value of the channel offset exceeds a threshold value, a direction of travel of the tape media is determined. In response to determining that the direction of travel of the tape media is a forward direction, a determination is made whether the channel offset is positive. In response to determining that the channel offset is positive, a first cooling device within the tape drive storage unit 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 media passing by a read/write head.
