摘要： A method and system for automatically running a program stored on a medium upon detection of insertion of the medium into a drive are provided. The operating system periodically polls the drive regarding the status of the drive. After receiving a response from the drive regarding the drive's status, the operating system determines whether the drive's status has changed. If the drive's status has changed, the operating system broadcasts a message indicating the change in the drive's status. When the shell receives a message from the operating system indicating a change in the drive's status, the shell determines whether the change in the drive's status indicates that a medium has been inserted into the drive. If the change in the drive's status indicates that a medium has been inserted into the drive, the shell searches for a predefined file on the medium. The shell then runs a program stored on the medium that is specified in the predefined file. Thus, the running of the program on the medium is performed without any action being required on the part of a user.

摘要： A method and system for caching data that improve the efficiency of a cache are provided. Generally, three types of data are stored in a cache constructed according to the principles of the present invention. These types of data include: (1) path tables, (2) directories, and (3) files. Path tables include data regarding all of the directories on a storage medium, directories include data regarding all of the subdirectories and files in each directory, and files include the actual file data. The preferred embodiment of the cache logically includes eight regions. These regions include (in order of preferred descending priority): (1) path table, (2) directory, (3) two-access, (4) zero-access or prefetch, (5) sequential-locked, (6) one-access, (7) discarded, and (8) invalid. The path table region includes sectors containing path table data, the directory region includes sectors containing directory data, the two-access region includes sectors containing file data that have been accessed twice, the prefetch region includes sectors containing file data that have been prefetched, the sequential-locked region includes sectors containing file data that were prefetched and have now been locked for access, the one-access region includes sectors containing file data that have been accessed once, the discarded region includes empty sectors that are available for reuse, and the invalid region includes a single dummy sector that is used as a placeholder. During operation, a cache manager manages the cache. The cache manager is responsible for manipulating the cache, such as by adding and removing sectors to and from the cache.

摘要： An encoder and method, such as for use in CD-ROM pre-mastering software, optimizes storage on a computer readable recording medium by eliminating redundant storage of identical data streams for duplicate files. The encoder and method detect whether two files have equivalent data streams, and encodes such duplicate files as a single data stream referenced by the respective directory entries of the files. In the illustrated embodiment, the encoder and method detect duplicate files based on file size and a cyclic redundancy check calculated on the file's data stream or portion thereof.

摘要： A method and system for dynamically converting audio data into a standard format. The method and system also provides for using a directory hierarchy to specify a fidelity level and dynamically generating the audio data at the specified fidelity level. When a drive is loaded with, for example, a CD ROM containing raw audio data, the system generates a directory hierarchy for the drive. The directory hierarchy contains sub-directories corresponding to various fidelity characteristics. For example, the system may generate a sub-directory corresponding to audio data stored in stereo format and another sub-directory corresponding to audio data stored in mono format. The system also generates a file entry in sub-directories for each track of the CD ROM. For example, the stereo sub-directory may contain a file entry for track 1 of the CD ROM and the mono sub-directory also may contain a file entry for track 1. The file in the stereo sub-directory represents the audio data in storage and the file in the mono sub-directory represents the audio data in mono. When accessing a file at a specified fidelity level (as indicated by the directory pathname), the system reads raw audio data from the CD ROM and converts the raw audio data to the fidelity level specified by the pathname.
摘要翻译：一种用于将音频数据动态转换为标准格式的方法和系统。该方法和系统还提供使用目录层次来指定保真度级别并以指定的保真级别动态生成音频数据。当驱动器加载有例如包含原始音频数据的CD ROM时，系统会为驱动器生成目录层次结构。目录层次结构包含与各种保真特性相对应的子目录。例如，系统可以生成对应于以立体声格式存储的音频数据的对应的子目录以及对应于以单声道格式存储的音频数据的另一个子目录。该系统还在CD ROM的每个轨道的子目录中生成文件条目。例如，立体声子目录可以包含CD ROM的轨道1的文件条目，并且单声道子目录还可以包含用于轨道1的文件条目。立体声子目录中的文件表示存储器中的音频数据单声道子目录中的文件以单声道形式表示音频数据。当以指定的保真度级别（如目录路径名指示）访问文件时，系统从CD ROM读取原始音频数据，并将原始音频数据转换为由路径名指定的保真级别。
