A data storage cartridge comprising a hard drive and a cartridge housing. The hard drive includes a non-tape storage medium and an electronic data connector including a plurality of connection pads for accessing the non-tape storage medium. The cartridge housing substantially encloses the hard drive. The plurality of connection pads are transversely accessible by a cartridge drive.

A recording system comprises a read-write head with a length that is substantially smaller than the width of the tape, the small mass of the head allows high frequency track following. The head contacts only that area of the tape currently being accessed, significantly reducing the tape and the head wear. The head flies over the tape with the flying height tightly controlled even at high tape speed and low tape tension. Several methods to stabilize the tape in the recording area are disclosed. The stabilizer can be a second recording head allowing dual sided recording. A first implementation uses a linear actuator and a second implementation uses a rotary actuator. A mechanism moves the head from the path of a threading mechanism.

System for high density linear serpentine data recording

A tape roller bearing is provided that prevents the development of an air film between the roller surface and the tape. The spool surface is made from porous material so that air flows through the spool surface. The porous material vents air uniformly over the roller surface, and the tape remains in direct contact with the roller, even at high speed. The speed of the tapes movement can be determined by measuring the speed of movement of the spool surface using an encoder disk and an encoder module.

Data tape speed tachometer using a porous roller bearing

A tape roller bearing is provided that prevents the development of an air film between the roller surface and the tape. The spool surface is made from porous material so that air flows through the spool surface. The porous material vents air uniformly over the roller surface, and the tape remains in direct contact with the roller, even at high speed. The inventive roller has many advantages, including improvement of tape wear characteristics, enhancement of tape guiding abilities, and increased tape speed stability.
