A audio data collection and management system is provided for extracting music data from an optical media and managing the music data. The system is configured to extract at least a portion of an initial track of music data at an extracting rate that is different than the recording rate. The system simultaneously records the extracted portion of the initial track of music data to a storage media at the extracting rate while performing the extracting. The system is configured to be implemented in an automobile, a home stereo system, or a personal computer system.

Audio system for storing audio data files

Disclosed is an automobile audio system. The automobile audio system includes a control panel for displaying audio data, and a control unit that is wired to the control panel. The control unit includes a hard disk and a compact disc player capable of playing at least one compact disc. Interface circuitry enables the wiring of the control unit to the control panel, and a processor and memory are connected to the interface circuitry. The memory is configured to store program instructions for extracting music data from the at least one compact disc and for recording the extracted music data to the hard disk.

Automobile audio system for collection, management and playback of audio data

A method and a system are provided to improve storage space utilization in a file management system with a fixed number of clusters without increasing the number of volumes visible to the user. This is accomplished by merging together multiple logical partitions created on a physical volume into a single virtual partition. This allows for the use of smaller, more efficient logical partitions while still presenting to the user/application a single large volume. As a result, the user is able to deal with a single volume, greatly reducing the burden of remembering on which volume each file is located, but, at the same time, the user is able to reap the benefits of the efficient storage allocation deriving from a reduced cluster size.

A method is provided for extracting music data from a compact disc and managing the music data. The method is configured to have the system extract at least a portion of an initial track of music data at an extracting rate that is greater than the listening rate. The system simultaneously writes the extracted portion of the initial track of music data to a storage media at the extracting rate while performing the extracting. Meanwhile, a user may listen to at least a portion of the extracted portion of the initial track of music data from the storage media at the listening rate.

Method and system for audio data collection and management

A method for writing compressed audio data to a compact disc media is provided. The method includes selecting songs to be written in a session and reserving a first track. After the first is reserved, the method proceeds to writing a first temporary data structure and audio data to a second track following the first track. After the second track is closed, part of first temporary data structure (e.g., the recompiled INFO.CD part) is written to the reserved first track and the session is closed. Another method includes beginning a session writing the compressed audio data to the compact disc media. A track that includes a file system and an audio data section is then written. The writing of the track further includes writing an INFO.CD file, writing an ISO file system, and writing a FILEINFO.LC file following the ISO file system. Once the audio data section is written, the method proceeds to closing the track and closing the session.

Methods for writing and reading compressed audio data

A method for writing compressed audio data to a compact disc media is provided. The method includes selecting songs to be written in a session and reserving a first track. After the first is reserved, the method proceeds to writing a first temporary data structure and audio data to a second track following the first track. After the second track is closed, part of first temporary data structure (e.g., the recompiled INFO.CD3 part) is written to the reserved first track and the session is closed. Another method includes beginning a session writing the compressed audio data to the compact disc media. A track that includes a file system and an audio data section is then written. The writing of the track further includes writing an INFO.CD3 file, writing an ISO file system, and writing a FILEINFO.LC file following the ISO file system. Once the audio data section is written, the method proceeds to closing the track and closing the session.
