US 2005/0031318 A1 · Data recording apparatus and system having sustained high transfer rates

Abstract

According to the invention, techniques for recording data onto recording media at relatively high transfer rates for relatively long periods of time. Embodiments according to the present invention include systems and apparatus capable of an improved sustained rate of data recording onto disk type-recording media, for example. Many embodiments can remove the upper limits of both recording capacity and the number of media that can be used. Select embodiments can be used with different kinds of recording media as well. In a specific embodiment, the area on a hard disk is divided into three areas. A first area can be suitable for sequential recording of continuous data. A second area can be suitable for random recording of discontinuous data. A third area can be used for recording logical sector numbers, coupling logical sector numbers, and file information that are used for marking each of the first and second areas, so that continuous data can be recorded on the hard disk at a high data rate.
