High Sierra Format

High Sierra Format (HSF) is the early logical file system used for compact discs. The ISO 9660 standard is based on revised HSF. The HSF standard was created in October of 1985 when representatives of 12 major computer hardware manufacturers (including Microsoft, Apple, Sony, Phillips, etc.), known together as the High Sierra Group, gathered at Del Webb's High Sierra Hotel and Casino (currently called the Horizon Casino) near Lake Tahoe, California.
