Abstract
A magnetic recording tape includes an elongated substrate and a magnetic film coated over the elongated substrate, where the magnetic film includes a first magnetic recording layer. The first magnetic recording layer includes particles having a diameter that is between a factor from about 2 to 5 greater than a thickness of the first magnetic recording layer.
Claims20
A magnetic recording tape comprising:
- an elongated substrate;
- and
- a magnetic film coated over the elongated substrate, the magnetic film including a first magnetic recording layer;
- wherein the first magnetic recording layer comprises particles having a diameter that is between a factor from about 2 to 5 greater than a thickness of the first magnetic recording layer.
1 more element
A magnetic recording tape comprising:
- an elongated substrate defining a first surface and a second surface opposite the first surface;
- and
- a first magnetic side coated over the elongated substrate, the first magnetic side comprising a first support layer coated on the first surface of the elongated substrate, a first magnetic recording layer coated on the first support layer, and particles disposed in the first magnetic recording layer;
- wherein the particles contact the first support layer and protrude out of the first magnetic recording layer, the particles adapted to configure the first magnetic recording layer to have a 5-pass static friction of less than about 80 grams force.
1 more element
A magnetic recording tape comprising:
- an elongated substrate defining a first surface and a second surface opposite the first surface;
- a first magnetic side coated over the first surface of the elongated substrate, the first magnetic side configured to provide a bit error rate of less than 1×10−6 for recording densities of between 180-210 kfci;
- and means for configuring the first magnetic side to have a 5-pass static friction of less than about 80 grams force.
