Bits on a harddisk

MFM measurements

The measurements shown here were taken with a Nanosurf Mobile S Large Scan head. The sample was a 10GB single head 3.5" harddisk magnetised in the plane of the medium with a track distance of 600 nm and a bit length of 70 nm, which corresponds to 42k TPI and 363k BPI
