Sony CDPCX455 Primary User Manual - Page 4

*1 ISO 9660 Format The most common international standard for the logical format of files and folders on a CD-ROM. There are several specification levels. In Level 1, file names must be in the 8.3 format (no more than eight characters in the name, no more than three characters in the extension ".MP3") and in capital letters. Folder names can be no longer than eight characters. There can be no more than eight nested folder levels. Level 2 specifications allow file names up to 31 characters long. Each folder can have up to 8 trees. For Joliet or Romeo in the expansion format, make sure of the contents of the writing software, etc. *2 Multi Session This is a recording method that enables adding of data using the Track-At-Once method. Conventional CDs begin at a CD control area called the Lead-in and end at an area called Lead-out. A Multi Session CD is a CD having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session. CD-EXTRA: A format in which CD-DA (audio) data are recorded in the tracks of session 1 and computer data in the tracks of session 2. Mixed CD: A format in which computer data are recorded in the first track and CD-DA (audio) data in the following tracks within a session. Notes • With formats other than ISO 9660 level 1, folder names or file names may not be displayed correctly. • When naming, be sure to add the file extension ".MP3" to the file name. • If you up the extension ".MP3" to a file other than MP3, the unit cannot recognize the file properly and will generate random noise that could damage your speakers. • The following discs take a longer time to start playback. - a disc recorded with complicated tree structure. - a disc recorded in Multi Session. - a disc to which data can be added (non-finalized disc). Cautions when playing a disc that is recorded in Multi Session CD-DA (audio) data or MP3 files stored on a Multi Session CD may be subject to some restrictions on playback. - If the disc begins with a CD-DA session, it is recognized as a CD-DA (audio) disc, and playback continues until an MP3 session is encountered. - If the disc begins with an MP3 session, it is recognized as an MP3 disc, and playback continues until a CD-DA (audio) session is encountered. - The playback range of an MP3 disc is determined by the tree structure of files produced by analyzing of the disc. - A disc with a mixed CD format will be recognized as a CD-DA (audio) disc. The playback order of the MP3 files The playback order of the folders and files is as follows: 1 1 2 2 Folder (album) MP3 file (tracks) 3 3 4 5 4 5 6 6 7 7 8 8 9 Tree 1 Tree 2 Tree 3 Tree 4 Tree 5 Notes • A folder that does not include an MP3 file is skipped. • When you insert a disc with many trees, it takes a longer time to start playback. We recommend that you make only one or two trees for each disc. • Maximum folder number: 150 (including root folder and empty folders) • Maximum total number of MP3 files and folders: 300 • The CD player can play the MP3 files in a folder whose depth in the folder tree is up to 8. Tip To specify a desired playback order, before the folder or file name, input the order by number (e.g., "01", "02"), then record contents onto a disc. (The order differs depending on the writing software.) Note on playback of MP3 files Depending on the encoding/writing software, recording device, or the recording media used at the time an MP3 file is recorded, you may encounter such problems as disabled playback, sound interruptions, and noise. 4US
