Abstract: An arcuate scan tape drive for transferring data to and from a data tape, including a base with four side walls and a cover, which base and cover together have a 31/2 inch form factor. In one embodiment, the head carrier assembly is provided at an oblique angle with respect to the data tape and the front surface is conically shaped. Thus, during rotation of the head carrier assembly, the recording heads are proximate to the data tape during read or write operations, but are spaced away from the data tape at other times. The head carrier assembly includes an inside-out spin motor for rotating the head carrier assembly and a pivot motor structure at the rear of the head carrier assembly for pivoting the head carrier assembly in a plane perpendicular to the longitudinal direction of advancement of the tape.

Abstract: A tape drive has a belt drive mechanism to rotate a cartridge roller. The belt drive mechanism includes a motor rotating a wheel mounted on a separate shaft using a belt. The movement of the belt is directly transferred to the cartridge roller due to the friction between the belt and the cartridge roller. A cushion of an elastomeric material is wrapped around the periphery of the wheel to cushion the belt and allows the belt to wrap slightly around the cartridge roller to increase the contact area of the belt on the cartridge roller and increase the life of the belt. Alternatively, the wheel may be of a rigid material and the belt of an elastomeric material.

Abstract: An arcuate scan tape drive for transferring data to and from a data tape, including a base with four side walls and a cover, which base and cover together have a 31/2 inch form factor. Situated within the base and cover is a head carrier assembly for recording data onto and playing back data from the data tape which advances in a longitudinal direction past the head carrier assembly. In one embodiment, the head carrier assembly is provided at an oblique angle with respect to the data tape and the front surface is conically shaped. Thus, during rotation of the head carrier assembly, the recording heads are proximate to the data tape during read or write operations, but are spaced away from the data tape at other times. Also provided within the base is a capstan motor assembly for advancing the data tape, and a cassette positioning mechanism for receiving and securing a data tape cartridge to properly position the tape as it is advanced past the head carrier assembly.
