Abstract
A tape drive has a tape transport system for use with a tape cartridge of the type having an exposed edge of the internal cartridge capstan. A stationary drive capstan fixedly mounted with respect to the tape drive chassis directly drives a compliant frictional drive roller connected thereto via a drive shaft. A combination of the compliance and friction characteristics of the drive roller material and/or the drive roller form factor achieves a contact pressure sufficiently high to engage the exposed edge of the internal cartridge capstan in order to transport the tape past a read/write head and yet sufficiently low to avoid damage to the tape cartridge or the tape drive.
