  • Patent number: 7164845
    Abstract: The present invention relates to a method for making multi-path data stream acceptable in a high-density recording medium. A data stream recording method according to the present invention, records data stream in a recording medium, groups multi-path stream section of the recorded data stream into a single stream object, creates time entries having location information indicating each boundary position between stream segments of different path wherein each time entry contains type information indicating whether related data stream interval is for multi-path or not, and records the created time entries. This multi-path data stream accepting method prevents searching error which might be caused from multi-path data stream in a high-density recording medium in reproducing mode.

  • Publication number: 20060123441
    Abstract: Provided is a small form factor optical/magnetic disk including an integrated metal hub and a disk plate. The integrated metal hub includes a circular upper metal hub and a circular lower metal hub integrally formed with and disposed under the upper metal hub. The circular lower metal hub has a smaller diameter smaller than the upper metal hub. A central hole is formed in central portions of the upper and lower metal hubs and passes through the upper and lower metal hubs. The disk plate has a through-hole that is formed in a central portion and is directly associated with the integrated metal hub, and a recess that is formed around the through-hole and allows the upper metal hub to be mounted therein. Since the central portion of the small form factor optical/magnetic disk is not thick, the small form factor optical/magnetic disk can contribute to an ultra thin small form factor information storage device. Also, since manufacturing processes are simple, price and quality competitiveness can be enhanced.
