摘要： In a recording disk cartridge, a plurality of flexible recording disk media is housed in a cartridge case, and a rotational member is provided to support the plurality of flexible recording disk media and cause them to rotate in unison within the cartridge case. The cartridge case has an opening to provide access to a first end of the rotational member from outside therethrough. A supporting shaft fitted to a portion on an axis of rotation of the rotational member near a second end thereof is slidable along the axis of rotation of the rotational member. A bearing ball is held between an inner surface of the cartridge case and an end of the supporting shaft protruding from a second-end face of the rotational member. An elastic member is provided between the supporting shaft and the rotational member, to press the rotational member toward the opening of the cartridge case.

摘要： A disk cartridge has a write protect portion for switching between a write-allowed state and a write-inhibited state. The write protect portion is equipped with two prisms having reflection faces different in reflectivity which are rotatably supported therein. In a drive device in which the disk cartridge is loaded, an amount of light, which is irradiated to the write protect portion and then reaches a photodetecting portion of the drive device, is varied by rotating a shaft. On the basis of the amount of the light reaching the photodetecting portion, the drive device judges whether the disk cartridge is in a write-inhibited state. According to the disk cartridge, dust-proof performance is not lost, and occurrence of mis-detection due to deformation of the disk cartridge can be prevented.

摘要： A magnetic disc cartridge includes a cartridge shell and a magnetic disc which is formed integrally with a center core member and is supported for rotation in the shell. The shell is provided with a magnetic head window through which a magnetic head of a recording and reproducing system is given access to the magnetic disc and a spindle hole through which a spindle of the recording and reproducing system is engaged with the center core member to rotate the magnetic disc with the center core member. There is disposed between at least one side of the magnetic disc and the inner surface of the shell opposed to the side of the magnetic disc a wobbling suppressing plate which is in the form of a substantially circular flat plate and is movable in the direction of the axis of rotation of the magnetic disc at least at its outer peripheral portion.

摘要： A magnetic disk cartridge has a cassette shell provided on its outer surface with at least two guide grooves located symmetrically on its outer surface to extend parallel to its direction of insertion into a magnetic disk cartridge drive device. The floors of the guide grooves are formed with teeth for enabling the magnetic disk cartridge to be automatically loaded and unloaded to and from a magnetic disk cartridge drive device by meshing of the teeth with an autoloading drive gear section provided in the magnetic disk cartridge drive device. The structure improves the dimensional precision of the cassette shell and provides the magnetic disk cartridge with autoloading capability.

摘要： A magnetic disk cartridge has a magnetic head access opening formed in one side surface of a flat cassette shell having a top surface, a bottom surface and side surfaces. A shutter member provided to be slidable on the cassette shell for opening and closing the magnetic head access opening is constituted as a sectionally U-shaped member formed by an upper wing, a shutter section having a window and a lower wing that are interconnected and extend respectively along the top surface, one side surface and the bottom surface. A shutter closing spring is provided for biasing the shutter member in the closing direction. The shutter section of the shutter member is provided at a lateral end portion thereof with a spring engaging portion for engaging one end of the shutter closing spring and between the spring engaging portion and the shutter window with at least one guide projection projecting toward the one side surface. The structure eliminates the problem of powder being produced owing to abrasion of the cassette shell because of unbalanced biasing of the shutter member by the shutter closing spring and ensures smooth sliding of the shutter member at all times.
摘要翻译：磁盘盒具有形成在具有顶表面，底表面和侧表面的扁平盒壳的一个侧表面中的磁头通路口。设置成能够在盒壳上滑动以便打开和关闭磁头通路口的活门构件构成为由上机翼，具有窗口的闸板部分和下机翼形成的截面U形部件，分别沿着顶表面，一个侧表面和底表面。提供了一个闭锁弹簧，用于沿关闭方向偏压挡板部件。闸门部件的闸板部分在其横向端部处设置有弹簧接合部分，用于接合闸板关闭弹簧的一端和弹簧接合部分与闸板窗口之间，其中至少一个引导突起朝向一侧突出表面。该结构消除了由于盒壳的磨损而导致的粉末产生的问题，因为挡板关闭弹簧对挡板构件的偏移不平衡，并且确保挡板构件始终平滑地滑动。
