摘要： A caching apparatus and method for enhancing retrieval of data from an optical storage device are provided. The apparatus preferably includes a first memory device for storing data therein. The first memory device preferably includes a predetermined application. An optical storage device is positioned in communication with the first memory device for optically storing data therein. The optical storage device includes a plurality of data storage sectors. A second memory device is positioned in communication with the first memory device for storing data. The second memory device preferably has a predetermined amount of data storage space. The predetermined amount of data storage space includes a caching space defined by only a portion of the predetermined amount of data storage space of the second memory device. A caching engine is positioned in communication with the first memory device, the second memory device, and the optical storage device for temporarily storing data from the data storage sectors in the caching space and thereby providing a quick transfer of the data to the first memory device for use by the predetermined application. An event script is provided positioned in communication with the caching engine to direct the caching engine to transfer data sectors from the optical data storage device to the caching space in advance of being actually needed for the predetermined application of the first memory device.

摘要翻译： 提供一种用于增强从光学存储设备的数据检索的高速缓存设备和方法。 该装置优选地包括用于在其中存储数据的第一存储装置。 第一存储器件优选地包括预定应用。 光学存储设备被定位成与第一存储器设备通信，用于在其中光学地存储数据。 光存储装置包括多个数据存储扇区。 第二存储器设备被定位成与第一存储器设备通信以存储数据。 第二存储器件优选地具有预定量的数据存储空间。 预定量的数据存储空间包括仅由第二存储装置的预定数量的数据存储空间的一部分限定的高速缓存空间。 缓存引擎定位成与第一存储器设备，第二存储器设备和光学存储设备通信，用于临时存储来自缓存空间中的数据存储扇区的数据，从而将数据快速传送到第一存储器设备 供预定应用使用。 事件脚本被提供定位成与缓存引擎通信，以引导高速缓存引擎在数据扇区从光学数据存储设备传输到高速缓存空间之前，实际上需要用于第一存储器设备的预定应用。
