摘要： An abrasive member comprises a non-magnetic substrate and a plurality of abrasive layers, which are overlaid upon the non-magnetic substrate, each of the abrasive layers mainly containing a binder and hard abrasive grains, which have a Mohs hardness of at least 6 and are dispersed in the binder. The plurality of the abrasive layers include a top abrasive layer and a lower abrasive layer, which is formed between the non-magnetic substrate and the top abrasive layer. The thickness of the top abrasive layer is at most A/2, where A represents the thickness of the lower abrasive layer. The mean grain diameter of the abrasive grains contained in the top abrasive layer is at most B/2, where B represents the mean grain diameter of the abrasive grains contained in the lower abrasive layer.

摘要： An abrasive member for a very high return loss optical connector ferrule is used in abrading an end of an optical connector ferrule having a ferrule hole, in which an optical fiber has been inserted and secured, into a convex spherical surface. The abrasive member comprises a flexible substrate and an abrasive layer, which is formed on the surface of the flexible substrate and comprises a binder and abrasive grains. The surface roughness Ra, expressed in terms of arithmetic mean deviation, of the abrasive layer falls within the range of 0.01 .mu.m to 0.05 .mu.m. The abrasive member carries out polishing such that the surface smoothness of the ferrule surface and the optical fiber surface may be kept high, such that a difference in level between the ferrule surface and the optical fiber surface may not occur, and such that the very high return loss characteristics may thereby be obtained.

摘要： A method for producing a magnetic recording medium is disclosed. The method involves providing a ferromagnetic coating layer on a non-magnetic support base to produce a coated base. The coated base is then subjected to an atmosphere having a RH of 60% or more, prior to or during a subsequent calendering treatment. The recording medium produced has excellent surface smoothness and improved electromagnetic properties. The method is advantageous in that a substantially long period of time may pass between the coating of the ferromagnetic layer on the support and the calendering treatment without having undesirable effects on the magnetic recording medium produced.
