Thus, although a method of reducing the width Wb of the openings 11a and 12a can be considered to make the disk cartridge 10 smaller, the width Wb of the openings 11a and 12a cannot be reduced as desired because the openings 11a and 12a must allow reading. device gets access to disk D

Embodiment Construction

[0017] Figure 4 A disk cartridge according to the present invention is shown.

[0018] refer to Figure 4 , the disk cartridge 20 includes: a shell with upper and lower covers 21 and 22, which form a space for housing the disk D; a clamper 23, which extends into the shell with the upper and lower parts 21 and 22 and engages therewith, while A supporting disk D; a shutter 24 for selectively opening or closing the openings 21a and 22a; and accommodation holes 21b and 22b formed in the upper and lower portions 21 and 22, respectively.

[0019] Here, the center lines C of the openings 21a and 22a are positioned to deviate from the centers C of the receiving holes 21b and 22b to one side by a predetermined distance d. That is, the center line C of the openings 21a and 22a is not located in the middle of the case with the upper and lower parts 21 and 22, and the widths W1 and W3 are set to be different from each other (W1>W3) so that the openings 21a and 22a are formed to be offs...

Abstract

A disk cartridge is disclosed. The disk cartridge is configured so that openings for allowing a pick-up to have access to a disk are formed to deviate toward one side from a middle position of the cartridge, and a shutter for opening / closing the openings can open the openings while moving in a direction opposite to the direction of deviation. With this configuration, since the size of the whole disk cartridge can be reduced while keeping the size of the openings as it is, it is advantageous that not only the disk cartridge itself but also a recording / reproducing apparatus for using the disk cartridge can be compacted.

Description

technical field [0001] The present invention relates to a disk cartridge for accommodating a magnetic disk as an information recording and reproducing medium, and more particularly, to a disk cartridge in which a The opening structure is improved, making it possible to advantageously reduce the size of the disk cartridge. Background technique [0002] Usually, such as figure 1 and 2 As shown, the disk cartridge 10 is used to accommodate the magnetic disk D used in the recording / reproducing apparatus 100, and includes: a case having upper and lower portions 11 and 12 forming an inner space for accommodating the magnetic disk D; device 13, which protrudes into and engages with the casing having upper and lower portions 11 and 12, while supporting the disk D; and 12a, so that the read head of the recording / reproducing apparatus 100 can get close to the magnetic disk D. Reference numerals 11b and 12b denote seating holes formed to connect with the open...
