A magnetic recording tape includes an elongated substrate and a magnetic side. The magnetic side includes a support layer formed over the substrate and a magnetic recording layer formed over the support layer to define a magnetic recording surface opposite the substrate. The magnetic recording layer includes magnetic particles and a lubricant and supports a net uncompressed density of at least 30 MB/in. The magnetic side has an extracted BET surface area of greater than 1.0 m/g.

Magnetic recording medium having improved durability for high density applications

A method for producing a magnetic recording medium includes heat-curing a coated substrate to cure a non-magnetic back coat on the substrate and to cure a magnetic front coat on the substrate, and calendering the heat-cured coated substrate to produce the magnetic recording medium. The calendering optionally is off-line calendering during which the substrate passes between opposed, generally non-compliant rolls. Other methods, and magnetic recording media produced by the disclosed methods, also are disclosed.

Heat curing and subsequent calendering to produce magnetic recording media

A magnetic recording medium including a substrate, a magnetic side, and a backside. The substrate defines a first surface and a second surface opposite the first surface. The magnetic side is formed over the first surface of the substrate and defines a recording surface. The backside is coated on the second surface of the substrate and is configured to decrease embossment of the recording surface. The backside defines a backside surface opposite the substrate. The backside surface having a skew less than about 0.5 and a kurtosis less than about 4.0.

Magnetic recording medium with backside to decrease recording surface embossment

A data storage tape cartridge ( ) includes two tape guides ( ). The tapes guides ( ) have a foil ( ) which is constructed from material which causes a wear pattern ( ) to be formed in the foil ( ), thereby removing localized forces and spreading out the forces and thereby decreasing the tape pressure.
