    摘要： A method for judging a coercive force of a magnetic recording medium, so recording magnetic information can be formed in either a low coercivity magnetic medium or a high coercivity magnetic medium by using a magnetic head. A magnetic information recording step writes magnetic information in the magnetic recording medium by alternately using a first write current suitable for writing in the low coercivity magnetic medium and a second write current suitable for writing in the high coercivity magnetic medium. A magnetic information reproducing step reproduces the magnetic information written in the magnetic recording medium. A judging step makes a judgment on a coercive force of the magnetic recording medium by way of comparing a first reproduced output A of the magnetic information written with the first write current and a second reproduced output B of the magnetic information written with the second write current.

    摘要： The present invention is directed to a process of making α-aminooxyketone and α-hydroxyketone compounds. The synthetic pathway generally involves reacting an aldehyde or ketone substrate and a nitroso substrate in the presence of a catalyst of the formula (IV): wherein Xa—Xc represent independently nitrogen, carbon, oxygen or sulfur and Z represents a 4 to 10-membered ring with or without a substituent and optionally a further step to convert the α-aminooxyketone compound formed to the α-hydroxyketone compound. The present invention results in α-aminooxyketone and α-hydroxyketone compounds with high enantioselectivity and high purity. The present invention is also directed to a catalytic asymmetric O-nitroso Aldol/Michael reaction. The substrates of this reaction are generally cyclic α,β-unsaturated ketone substrate and a nitroso substrate. This methodology generally involves reacting the cyclic α,β-unsaturated ketone substrate and the nitroso substrate in the presence of a proline-based catalyst, to provide a heterocyclic product.
