oer·sted (Oe),

(er'sted),
A unit of magnetic field intensity; the magnetic field intensity that exerts a force of 1 dyne on a unit magnetic pole; equal to (1000/4π) A m-1.
[Hans-Christian Oersted, Danish physicist, 1777-1851]

oer·sted

(er'sted)
A unit of magnetic field intensity; the magnetic field intensity that exerts a force of 1 dyne on unit magnetic pole; equal to (1000/4π) A·m-1.

oersted

(ĕr′stĕd)
[Hans Christian Oersted, Danish physicist, 1777–1851]
A unit of magnetic field intensity. An oersted is the magnetism that exerts a force of one dyne on a unit magnetic pole. This term has largely been replaced by the SI unit amperes per meter.

Since low magnetic moment samples are usually thin films on bulk substrates, SRMs have to be specified with low intrinsic coercivity to minimize diamagnetic effects due to the substrate.
Tapes are used frequently for interchange and thus must meet coercivity specifications.
Generating much more coercivity than recording heads (used for overwriting), the highest rated AC degaussers available generate about 4,000 Oe.
With a 20GB native capacity and a 3MB/sec uncompressed transfer speed, it utilizes a high coercivity metal particle tape for high recording density and efficient encoding schemes.
But they're also working to boost the coercivity of the media (in effect, its "willingness" to have the grains' polarities re-oriented).
