• Particulate media composed of small particles were studied in their high-density recording performances and thermal stability. Media include metal particulate media consisting of mean length of 71, 102 and 48 nm, and Ba ferrite particulate media consisting of mean thickness of 22, 28 and 50 nm. Using a loss-term simulation program, which takes into account gap-loss, spacing-loss and particle length loss, the recording capability (D_<20> of 265 kFRPI for MP and 290 kFRPI for Ba ferrite media) was estimated. Thermal stability was evaluated from the magnetization time decay measurement. It was found that MP media were stable and Ba ferrite media were less stable but within a practically allowable range.
