  • High density optical disk having capacity of 25GB
    Patent number: 7088666
    Abstract: A high density disc having a data area which is set such that compatibility is secured in the same drive while maintaining a superior recording/reproducing feature, is disclosed. The high density disc has a center hole, a clamping area, a data area where user data is recorded, a lead in area located at the inner side of the data area, and a lead out area located at the outer side of the data area. In the high density disc in which the diameter of the center hole is 10 mm or more, the inner diameter of the clamping area is characteristically within a range of 20–26 mm. Also, the inner diameter of the data area is characteristically within a range of 35–40 mm. Therefore, while a conventional disc drive is still used, the size of the high density disc decreases and a recording capacity can be increased.

  • Disk cartridge
    Patent number: 7089574
    Abstract: A disk cartridge includes a case which receives a disk thereon, a cover which is installed on the case and includes an opening, and a shutter which is movably installed in the case, in a lower direction of the disk, to open and close an aperture formed on the case. The disk cartridge has guide holes formed on the case along a trace of the shutter, and support members formed on the shutter. The support members are guided along the guide holes while having ends thereof interfering with peripherals of the guide holes. Therefore, since the peripherals of the guide holes interfere with the ends of the support members, the shutter is prevented from being deformed even where an external force is applied to the shutter through the aperture, in a closed state of the shutter.

  • Methods for fabricating fin field effect transistors using a protective layer to reduce etching damage
    Patent number: 7074662
    Abstract: A method of forming a fin field effect transistor on a semiconductor substrate includes forming a vertical fin protruding from the substrate.
