Tape cartridge having tape media having synergistic magnetic recording layer and underlayer

Abstract:

A tape cartridge, according to one approach, includes a housing, and a magnetic recording tape at least partially stored in the housing. The magnetic recording tape including a recording layer having encapsulated nanoparticles each comprising a magnetic nanoparticle encapsulated by an encapsulating layer, and a polymeric binder binding the encapsulated nanoparticles. A tape cartridge, according to another approach, includes a housing, and a magnetic recording tape at least partially stored in the housing. The magnetic recording tape include an underlayer having encapsulated nanoparticles each comprising a magnetic nanoparticle encapsulated by an aromatic polymer, and a polymeric binder binding the encapsulated nanoparticles.
