ISO 9660, also referred to as CDFS (Compact Disc File System) in Microsoft Windows, is a file system standard published by the International Organization for Standardization (ISO) for optical disc media. It aims at supporting different computer operating systems such as Windows, classic Mac OS, and Unix-like systems, so that data may be exchanged. ==History== ISO 9660 traces its roots to the High Sierra Format file system. High Sierra arranged file information in a dense, sequential layout to minimize nonsequential access by using a hierarchical (eight levels of directories deep) tree file system arrangement, similar to UNIX and FAT. To facilitate cross platform compatibility, it defined a minimal set of common file attributes (directory or ordinary file and time of recording) and name attributes (name, extension, and version), and used a separate system use area where future optional extensions for each file may be specified. High Sierra was adopted in December 1986 (with changes) as an international standard by Ecma International as ECMA-119 〔(【引用サイトリンク】 title=Volume and File Structure of CDROM for Information Interchange )〕 and submitted for fast tracking to the ISO, where it was eventually accepted as ISO 9660:1988. In 2013, ISO published Amendment 1 to the ISO 9660 standard, introducing new data structures and relaxed file name rules intended to "bring harmonization between ISO 9660 and widely used 'Joliet Specification'."〔ISO 9660, Amendment 1 (ISO 9660:1988/Amd.1:2013(E))〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ISO 9660」の詳細全文を読む スポンサード リンク
