The data bits stand up rather than lay flat.
Or something like that.
It's the way Seagate increased the data density on the disc.
Greatest thing since sliced bread I hear.
With longitudinal (standard) recording each bit has a north pole followed by a south pole, or a south pole followed by a north pole, depending on whether the bit is a zero or a one.
With perpendicular recording the north pole is on the surface and the south pole is on the lower layer (or the other way round) allowing for much greater densities.
