Abstract

A cassette tape is constructed so that a radius of one reel side in a condition where to a middle point of a magnetic tape wound on a reel with a same radius k is a radius of a large-diameter reel, and the radius k is a radius of a small-diameter reel. With the cassette tape of the above construction, information corresponding to each other recorded on one track and the other track parallel to each other of a magnetic recording medium can be easily dubbed without deteriorating the interrelationship of information between both tracks.
