Abstract: A write area (10) is formed as a writable area on a recording medium accommodating cassette by a printing process using a printing ink containing a proper amount of protein powder made of natural collagen as a main component. In the write area (10), owing to hydrophilic group of the protein powder, even when something is written therein with a water base pen, its ink can be prevented from being floated therefrom and hence the writing can be carried out satisfactorily.

Abstract: A method of preparing gamma ferric hydroxyoxide in which ferrous ions are reacted in an alkaline solution to produce a suspension of ferric hydroxide, the resulting suspension is treated with an oxidizing gas in a first oxidizing step at a relatively high oxidation rate, sufficient to cause nucleation of gamma ferric hydroxyoxide to occur, and then the oxidation rate is reduced in a second oxidizing step to cause crystal growth to occur on the nuclei formed in the first oxidizing step. The resulting product has magnetic and physical characteristics making it extremely suitable for use in the manufacture of magnetic recording media.
