Problems solved by technology

By narrowing the track, the position control free area becomes relatively large compared to the servo field, and thus it is difficult to achieve sufficient precision track control (track following) in the conventional sector servo system having several servo fields.
Track control accuracy can also be improved by increasing the number of servo fields, but in the sector servo method, since data fields and servo fields are provided in the data track, when the number of servo fields increases, there are fewer data areas The problem

Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0030] figure 1 The first embodiment of the magnetic recording medium of the present invention is shown. figure 1 It is a partially enlarged view of the recording and reading layer of the magnetic recording medium. The magnetic recording medium is a disk-shaped magnetic recording medium such as a high-density floppy disk, and has a structure in which a recording and reproducing layer composed of a magnetic layer is provided on a flexible substrate. In addition, in particular, in order to achieve high density, it is preferable to use a thin-coated magnetic layer, a metal thin film magnetic layer, or the like as a recording and reading layer.

[0031] Such as figure 1 As shown, on the recording and reading layer of the magnetic recording medium, a data track D and a guard band G are sequentially formed adjacent to each other, and a magnetic pattern 10 carryin...

Abstract

In a flexible magnetic recording medium having a track width of about 1 to 3 μm, good track control can be performed. A magnetic pattern (10) carrying a servo signal is provided in a guard band G formed on both sides of a data track D of a magnetic recording medium (2) to perform continuous servo, thereby improving track control accuracy.

Description

technical field [0001] The present invention relates to a magnetic recording medium, in particular to a flexible and movable magnetic recording medium having signals for tracking servo. [0002] In addition, the present invention also relates to a drive device for driving a magnetic recording medium. Background technique [0003] As the amount of information increases, the magnetic recording medium is generally desired to be a large-capacity, inexpensive medium that can record a large amount of information, and preferably a so-called high-speed access medium that can read a desired location in a short time. As an example, High-density magnetic recording media such as ZIP (Aiomega Corporation) composed of hard disks and floppy disks are known. Compared with floppy (R) disks, these high-density magnetic recording media have information recording areas composed of narrow tracks, and the magnetic head accurately scans the narrow track width to reproduce signals with high S / N, s...
