Abstract
We observed thermomagnetically recorded domains of various sizes with magne tic transmission X-ray microscopy (M-TXM) in order to clarify the recording characteristics. The domains were recorded on TbFeCo films by laser-pumped magnetic field modulation (LP-MFM) using a 635 nm laser diode. Typical ima ges of magnetic domains in TbFeCo films were taken at the Fe L-3-edge, and it was confirmed that the crescent-shaped domains could be recorded with hi gh quality for mark lengths down to 100 nm.
