Claims

[Claims for Utility Model Registration] (1) A magnetic disk cartridge comprising a housing equipped with a magnetic disk rotation drive mechanism, a frame equipped with a magnetic disk clamping mechanism and a magnetic disk cartridge ejection mechanism. is introduced into the housing to record or reproduce information, or to record and reproduce information, the first positioning portion is formed at a housing position a preset distance from the rotation center of the spindle of the rotational drive mechanism. At the same time, a second positioning part is formed at a frame position the same distance as the distance set as above from the center of rotation of the hub of the clamp mechanism, and the first and second positioning parts are aligned. The frame is attached to the housing, and furthermore, the contact portion of the ejection member that defines the position of the magnetic disk cartridge with the magnetic disk cartridge and the rotation center of the hub are aligned with the predefined rotation center position of the magnetic disk cartridge. A third positioning portion is provided on the frame and a fourth positioning portion is provided on the mounting plate of the ejection mechanism so as to correspond to the distance between the ejection member of the magnetic disk cartridge and the edge of the case that abuts. The positioning part of
A magnetic disk drive device, characterized in that the mounting plate is attached to the frame so as to match the positioning portion of the frame. (2) In paragraph (1) of claims for utility model registration,
A magnetic disk drive device, wherein each of the first and second positioning portions is an insertion hole. (3) In paragraph (1) of claims for utility model registration,
A magnetic disk drive device characterized in that the third positioning portion and the fourth positioning portion are composed of a combination of a fitting hole and a fitting protrusion.
