Abstract

The magnetic record / reproduce apparatus for recording and reproducing large amounts of data at ultra-high-speed using a perpendicular magnetic recording mode, comprises: at least a cylinder having a perpendicular magnetic recording layer provided on at least the inner or outer surface thereof; a plurality of magnetic heads arranged to face the perpendicular magnetic recording layer of the cylinder; a rotating means for rotating at least one of the cylinder and the plurality of magnetic heads in relation to the other; a linear driving means for moving at least the cylinder or the plurality of magnetic heads along the axial direction of the cylinder; and a record / reproduce means for recording and / or reproducing data on the perpendicular magnetic recording layer.

Description

technical field [0001] The present invention relates to a data recording / reproducing device and more particularly to a perpendicular magnetic recording / reproducing device for recording / reproducing a large amount of data at an ultrahigh speed. Background technique [0002] Since the modern trend of participation in the Internet society is rapidly expanding, it promotes the combination of communication technology and computer technology and accelerates the development of various software. Therefore, multimedia data including still and moving video data and audio data is widely used and the total amount of such data to be handled for various purposes is remarkably increased. This basically requires a large-capacity data storage as a database. Also, in the sudden appearance of many Internet users, an advanced on-demand instant response system is required so that an unlimited number of users can freely access the database. In other words, a high-speed operation and a large stor...
