Abstract: According to one embodiment, a method for storing data on a magnetic tape comprises receiving data from two different hosts and simultaneously writing the data from the hosts to the magnetic tape using multi-ple transducers. In another approach, a method for stor-ing data on a magnetic tape comprises receiving requests to establish a concurrent reservation from multiple hosts and allocating a unique stripe in a wrap to each of the hosts that sent the requests, wherein the wrap is a collec-tion of data tracks to be written simultaneously in one di-rection of tape movement by multiple transducers of a tape head, and the wrap is logically divided into the stripes. Also, the method includes receiving data from the hosts and simultaneously writing the data from the hosts to the magnetic tape using the multiple transducers. Oth-er systems and methods concerning storing data on mag-netic tapes are described as well.

In another approach, a method for storing data on a magnetic tape comprises receiving requests to establish a concurrent reservation from multiple hosts and allocating a unique stripe in a wrap to each of the hosts that sent the requests, wherein the wrap is a collection of data tracks to be written simultaneously in one direction of tape movement by multiple transducers of a tape head, and the wrap is logically divided into the stripes. Also, the method includes receiving data from the hosts and simultaneously writing the data from the hosts to the magnetic tape using the multiple transducers. Other systems and methods concerning storing data on magnetic tapes are described as well.
