Problems solved by technology

In this system, since the recording medium 1018 is subjected to external forces in various directions when the cartridge is carried, it is impossible to prevent the recording medium 1018 from vibrating or to prevent the gap 1081 from being generated between the core 1080 and the lower case 1016, resulting in Yes, there is a problem that the recording medium 1018 is cracked or the recording medium 1018 is contaminated

Embodiment Construction

[0048] The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0049] These embodiments are preferred specific examples of the present invention. Therefore, various preferred technical limitations are imposed on the embodiments. However, in the following description, the scope of the present invention is not limited to these embodiments unless it is explained that the present invention has Specific restrictions.

[0050] figure 1 A preferred embodiment of a recording medium drive mechanism including a disk cartridge according to the present invention is shown.

[0051] figure 1 The recording medium drive mechanism shown is a so-called replaceable hard disk drive mechanism (R-HDD). The replaceable hard disk drive mechanism is a replaceable disk drive mechanism. The structure of the replaceable hard disk drive mechanism 1 allows the disk cartridge 15 to be placed in and taken out of it.

Abstract

A rotor is provided which is rotatably disposed between a first shell and a recording medium, in a containing space formed inside the first shell and a second shell. The rotor includes a first wall formed along the circumferential direction of the rotor, and a part of the first wall is cut out to form a first opening. The second shell includes a second wall formed so as to overlap with the inside of the first wall along the outer circumference of the recording medium, on the outside in the radial direction of the outer circumference of the recording medium. The second wall and the first wall constitute a labyrinth structure portion for isolating the recording medium and the exterior of the recording medium from each other. With the rotor rotated, the first opening and a second opening constitute a head in/out opening.

Description

Technical field [0001] The present invention relates to a disk cartridge containing a disk-shaped recording medium, which can be set in and taken out of a recording medium drive mechanism; and relates to a recording medium drive mechanism including the disk cartridge. Background technique [0002] The recording medium drive mechanism can be incorporated into an electronic device that records and reproduces information, such as a portable computer. [0003] Such a recording medium drive mechanism can removably place a magnetic disk cartridge, which contains a disk-shaped recording medium. For example, the disk-shaped recording medium may be a hard disk, which is designed to magnetically record information on the recording medium, and can copy the information recorded on the recording medium. [0004] Such a recording medium drive mechanism is called a replaceable hard disk drive mechanism (R-HDD). [0005] Figure 12 shows an example of a conventional replaceable hard disk drive me...
