Enhanced CD
An Enhanced CD is an audio CD that includes CD-ROM data such as video, photos,
web links and more. In an audio player, an E-CD simply plays music or audio,
but on a PC or Mac, it launches the additional content such as data, pictures,
video, HTML content, PDF documents, etc.
We can create your Enhanced CD to be PC and Mac compatible and include an
autorun feature (not available on OS X). Call us for more details.
CD-ROM
The most common size of CD-ROM disc is 120 mm in diameter, though the smaller
Mini CD standard with an 80 mm diameter, as well as numerous non-standard sizes
and shapes (e.g. business card-sized media) are also available CD-ROMs are
popularly used to distribute computer software, including games and multimedia
applications, though any data can be stored (up to the capacity limit of a
disc).
A standard 120 mm CD-ROM holds up to 650MB of data.
Hybrid CD-ROM
A Hybrid disc is a CD-ROM that has multiple file systems, so that it can be
used on various system software, for example both Apple Macintosh and Microsoft
Windows based operating systems.
A hybrid disc has multiple file systems installed on it, typically ISO 9660 and
HFS+ (or HFS on older discs). The reason for the format is primarily that ISO
9660 has severe restrictions placed on filenames (initially only 8 characters
per file, and a depths of 3 directories) and lacks key structures present in
Apple Computer's HFS and HFS+ file systems. Another key factor is that ISO 9660
does not support resource forks, which is critical to Mac OS' software design
(Mac OS X has removed much of the emphasis/need for resource forks in
application design). Companies that released products for both DOS (later
Windows) and Mac OS (later Mac OS X) could release a CD containing software for
both, natively readable on either system. Data files can even be shared by both
partitions, while keeping the platform specific data separate. In a true (or
shared) hybrid HFS filesystem, files common to both the ISO 9660 and HFS
partitions are stored only once, with the ISO 9660 partition pointing to file
content in the HFS area (or vice versa).
