It can play Blu-ray disc or its ISO files not only on Mac, but also on iPhone/iPad/iPod touch. There are various modes available in the interface which includes read, write, built, verify and discovery.Blu-ray Player for Mac is the first universal media player for Mac in the world. It is lightweight burning application and can perform burning of CD, DVD, Blu-ray disc and HD DVD. ImgBurn is the ISO burner free for download and has plenty of advanced features.

The primary volume descriptor provides information about the volume, characteristics and metadata, including a root directory record that indicates in which sector the root directory is located. An ISO 9660 compliant disc must contain at least one primary volume descriptor describing the file system and a volume descriptor set terminator which is a volume descriptor that marks the end of the descriptor set. The rest begins with a volume descriptor set (a header block which describes the subsequent layout) and then the path tables, directories and files on the disc. Subsequent amendments to the standard were published in 20.The first 16 sectors of the file system are empty and reserved for other uses. High Sierra was adopted in December 1986 (with changes) as an international standard by Ecma International as ECMA-119 and submitted for fast tracking to the ISO, where it was eventually accepted as ISO 9660:1988. 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.

This group became known as the High Sierra Group ( HSG). In September/ October 1985 several companies invited experts to participate in the development of a working paper for such a standard.In November 1985, representatives of computer hardware manufacturers gathered at the High Sierra Hotel and Casino (currently called the Hard Rock Hotel and Casino) near Lake Tahoe, California. In order to develop a CD-ROM file system standard ( Z39.60 - Volume and File Structure of CDROM for Information Interchange), the National Information Standards Organization (NISO) set up Standards Committee SC EE (Compact Disc Data Format) in July 1985.

The ECMA submitted their standard to the International Standards Organization (ISO) for fast tracking, where it was further refined into ISO 9660. With changes this led to the issue of the initial edition of the ECMA-119 standard in December 1986. The High Sierra Group Proposal ( HSGP) was released in May 1986.A draft version was submitted to the European Computer Manufacturers Association (ECMA). The meeting report evolved from the Yellow Book CD-ROM standard for data CDs, which was so open ended it was leading to diversification and creation of many incompatible data storage methods.

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'.' In December 2017, a 3rd Edition of ECMA-119 was published that is technically identical with ISO 9660, Amendment 1. It was withdrawn before final approval, in favour of ISO 9660. The international extensions are the bulk of the differences between the formats.In order not to create incompatibilities, NISO suspended further work on Z39.60, which had been adopted by NISO members on. ECMA-119 and ISO 9660 were needed because the HSF was geared primarily towards the needs of the US market. ISO 9660:1988 was published in 1988.

Volume descriptor set The data area begins with the volume descriptor set, a set of one or more volume descriptors terminated with a volume descriptor set terminator. While it is suggested that they are reserved for use by bootable media, a CD-ROM may contain an alternative file system descriptor in this area, and it is often used by hybrid CDs to offer classic Mac OS-specific and macOS-specific content. Top level ISO 9660 file systemThe system area, the first 32,768 data bytes of the disc (16 sectors of 2,048 bytes each), is unused by ISO 9660 and therefore available for other uses. Both-byte order is required in several fields in the volume descriptors and directory records, while path tables can be either little-endian or big-endian. Specifications The following is the rough overall structure of the ISO 9660 file system.Multi-byte values can be stored in three different formats: little-endian, big-endian, and in a concatenation of both types in what the specification calls 'both-byte' order.

The volume descriptor set terminator is simply a particular type of volume descriptor with the purpose of marking the end of this set of structures. Redundant copies of each volume descriptor can also be included in case the first copy of the descriptor becomes corrupt.Standard volume descriptor types are the following:Supplementary volume descriptor, or enhanced volume descriptorAn ISO 9660 compliant disc must contain at least one primary volume descriptor describing the file system and a volume descriptor set terminator for indicating the end of the descriptor sequence. They have the following structure:The data field of a volume descriptor may be subdivided into several fields, with the exact content depending on the type.
