An apparatus may include a first magnetic layer, a first exchange break layer formed on the first magnetic layer, a second magnetic layer formed on the first exchange break layer, a second exchange break layer formed on the second magnetic layer, and a third magnetic layer formed on the second exchange break layer. The first magnetic layer has a first magnetic anisotropy energy, H.sub.k1, the second magnetic layer has a second magnetic anisotropy energy, H.sub.k2, and the third magnetic layer has a third magnetic anisotropy energy, H.sub.k3. In some embodiments, H.sub.k1H.sub.k2 is less than H.sub.k2H.sub.k3. In some embodiments, the apparatus may be a perpendicular magnetic recording medium.

A perpendicular magnetic recording medium includes a perpendicular magnetic layer provided above a nonmagnetic substrate, and a protection layer provided on the perpendicular magnetic layer. The perpendicular magnetic layer has an hcp structure, and includes stacked layers having a (0002) crystal plane oriented parallel to a surface of the nonmagnetic substrate. An uppermost layer amongst the stacked layers includes polycrystal grains selected from a CoCr-base alloy, a CoPt-base alloy, a CoCrPt-base alloy, and a CoPtCr-base alloy. The protection layer makes contact with the uppermost layer of the perpendicular magnetic layer, and includes a single graphene layer or a graphene stack, and an amorphous carbon layer. The single graphene layer or the graphene stack is bonded in parallel to a (0002) crystal plane of the polycrystal grains.

The present invention is an applications gateway that offers multiple functions and features for specific geographic venue locations, while providing easy access to advertising, purchasing, and redemption opportunities for that specific geographic venue location. Venue locations can be stadiums, shopping malls, amusement parks, open air spaces where people can congregate, and/or buildings, which most often require the presence of a concentration of people. The venue location may correlate to the location of the hand-held mobile unit or it may be a remote geographic venue location not near the location of the hand-held mobile unit. Access to the gateway application is through a hand-held mobile unit, which can include a mobile phone, smartphone device, or portable computer having a wireless radio transmission connection. (e.g. iPhone, Droid, iPad, Slate, etc.)

According to one embodiment, a perpendicular magnetic recording medium includes an underlying layer with convexes arranged with 1 to 20 nm intervals, and a multilayered amorphous magnetic recording layer formed on the underlying layer. The multilayered amorphous magnetic recording layer includes a first amorphous magnetic recording layer with a plurality of magnetic grains each formed on a corresponding convex to be widened toward its tip and being separated from each other at least in the convex side, a nonmagnetic protective layer covering at least a part of a sidewall of the magnetic particle, and a second amorphous magnetic recording layer formed on the nonmagnetic protective layer.
