Date: Wed, 6 Apr 1994 09:59:11 GMT References: Lines: 52 First, the term "WORM" is normally used to refer to real write-once-read-many media. The sector structure/recording format of WORM is quite different than that of CD, so the normal term for "worm" cd is CD-WO. Generally, CD or CD-WO drives cannot read WORM disks as the underlying recording format is quite different. Not all CD drives can read all disks produced using CD-WO drives as CD-WO provides for recording techniques, e.g., incremental recording, that are not understood by CD readers. If there isn't already, a description of the different recording formats should be put in a FAQ. Actually, pages 107-119 of ECMA-168 (ISO/IEC DIS 13490) provides some of this info. ECMA-168 is available at ftp.cdrom.com, or at least it used to be. Note that ISO/IEC DIS 13490 has been significantly editorially, at least, altered and is in the final stages of editing before being submitted to ISO for publication. However, the pages in the current draft may be of assistance in answering the concerns below. Upon completion of this editing, it is expected that a revised edition of ECMA-168 will be produced to conform to changes in ISO/IEC 13490. It is hoped that this revised edition will be published before the end of the year, perhaps as early as June. If permitted, I will try to make it available via ftp (or people could use ftpmail to get it if they do not have direct ftp access).
