摘要:
A disc cartridge of the present invention has magnetic means provided on an inner surface at least one of a pair of housing means which faces information recording means and acting on a hub for fixing a magnetic disc so that the magnetic disc is prevented from being vibrated in the disc cartridge. In consequence, the present invention provides a disc cartridge which operates at a high reliability and in which foreign matter such as dust is not produced.

A magnetic recording disk cartridge comprises a magnetic recording disk accomodated for rotation in a casing. The magnetic recording disk is provided with a center core having a central opening into which a spindle of a magnetic recording/reproducing system is inserted to be drivingly engaged therewith. The center core comprises a core block provided with the central opening and a pair of slits formed in the wall portion of the core block defining the central opening and spaced from each other by a predetermined distance; and a plate spring which extends across the central opening and the opposite end portions of which are fitted into the slits and held therein so that the plate spring can be resiliently deformed in a direction radial to the magnetic recording disk. When the spindle is fitted into the central opening, the plate spring is pushed by the spindle to be resiliently deformed, and the outer pheripheral surface of the spindle is urged radially inwardly by the resiliency of the plate spring so that the rotational axis of the spindle coincides with the central axis of the magnetic recording disk.

A small form factor disc drive is structured to hold and play an optical data storage disc measuring approximately 32 mm in diameter and containing 1 GB of data per layer. The disc drive contains a blue wavelength laser, an objective lens having a numerical aperture in the range of 0.70-0.78 and conventional DVD-compatible controller electronics. This unique combination of elements allows a full-length movie or a video game to be displayed with DVD-quality on a cell phone or other portable hand held device.

A recording disk cartridge includes a plurality of flexible recording disk media, a rotational member, and a cartridge case. The rotational member holds the recording disk media so that the recording disk media simultaneously rotate. The cartridge case provides a rotationally free housing for the recording disk media and the rotational member. The cartridge case has an opening to allow an end portion of the rotational member to be exposed to an outside of the cartridge case. The recording disk cartridge has an elastic member which provides a force to thrust the rotational member toward the opening.

A removable magnetic data storage cartridges incorporates antiferromagnetically coupled (AFC) media and may be used with a data drive to push the capacity point of removable hard platter based magnetic storage to 35 GB for a single platter 2.5″ form factor product. The removable magnetic data storage cartridges incorporating AFC media represents an equivalent increase in the areal density of removable magnetic data storage cartridges on the order of 13×.
摘要:
The object of the present invention is to provide a technology which has high compatibility and can provide users with conveniences. A new system recording medium 100 has a center hole 112 formed on a recording disk 110 and a center hole 121 formed on a center hub 120, so that the recording medium 100 can respond to both an old system driving unit having a centering member coupling with the center hole 112 and a new system driving unit 300 having a second centering member 313 coupling with the center hole 121. Moreover, the old system recording medium is a recording medium providing a recording disk having a center hole incorporated in a cartridge having a center hub, and has a structure where the center hole is coupled both with a first centering member 312 of the new system driving unit 300 and with the centering member of the old system driving unit.
