US 2004/0167643 A1 · Data processing method of a virtual optical disk

Abstract

A data processing method of a virtual optical disk applied in an optical disk system is provided. The method includes steps as follows: Firstly a sound source determining procedure is executed. If the sound source is not from a virtual optical disk, a pre-processing and a buffer playing process are executed, and also a state changing process is executed while the buffer playing process is executed. According to a result of the state changing process, one of the following three steps is executed: the sound source determining procedure, the pre-processing procedure, and an idle determining procedure. If the system is not idling when executing the idle determining procedure, the buffer playing process is thus executed. Otherwise, a state assessment process is then executed. In accordance with the state assessment process, a storage capacity planning procedure, a write process or the state changing process is then executed.
