日本东京芝浦电气公司最近宣布,试制成功垂直磁记录方式的小型大容量盒式软磁盘,同时试制了与之配套的读取和存储装置。该公司在规格统一等方面尚需花一段时间,计划两年后可批量生产。垂直磁记录是相对于记录介质面进行垂直方向记录信息的新方法,与通常的平行记录方式相比,有可能大幅度提高记录密度。一九七五年日本东北大学岩崎俊一教授首先
Japan’s Shibaura Electric Co., Ltd. recently announced the trial production of small vertical magnetic recording of large-capacity flexible disk cartridges, while the trial production of the accompanying reading and storage devices. The company still takes some time in terms of uniform specifications and plans to mass-produce in two years. The perpendicular magnetic recording is a new method of recording information in the vertical direction with respect to the surface of the recording medium, and it is possible to significantly improve the recording density as compared with the conventional parallel recording method.
