Abstract

The present invention relates to a magnetic recording medium, performing patterning to tiny size of magnetic area correspondingly to the inclined slide rod for augmenting storage capacity. A magnetic recording medium on which a plurality of concentric recording tracks is formed, the recording tracks including a plurality of closed shaped magnetic parts formed to be symmetrical with respect to two orthogonal axes in shape, the magnetic recording medium being rotated by a recording and reproducing apparatus provided with a slider including a recording and reproducing head to record or reproduce a magnetic recording, wherein when the recording and reproducing head which is moved with movement of a slider to record data on or reproduce data from the recording tracks is inclined by a predetermined angle with respect to a tangent line of concentric circles of the recording tracks, the slider moving in a radial direction of the concentric circles of the recording tracks, one of the two orthogonal axes of the magnetic parts is perpendicular to the recording and reproducing head.

Description

technical field

[0001] The present invention relates to a magnetic recording medium with increased storage capacity, and a recording and reproducing device for taking out a magnetic recording medium among a plurality of magnetic recording media stored in a cartridge, and recording or reproducing data. Background technique

[0002] With the configuration of the communication environment and the development of electronic technology, the amount of information processed by information-related devices has increased significantly. In response to such environmental changes, the functions and processing capabilities of information-related devices such as personal computers have also been dramatically improved. In order to cope with the increase in the amount of information, increasing the capacity of a recording medium storing information is one of the important issues.

[0003] In order to solve this problem, a technique has been disclosed in which recording cells separated from e...
