|
||
|
|
<div><p>i5/OS™ provides
|
||
|
|
support for several optical media types and media formats.</p>
|
||
|
|
<p> The media format is the file system architecture that exists on the media
|
||
|
|
to manage file, directory, and volume information.</p>
|
||
|
|
<p>Writable optical media (such as WORM, erasable, DVD-RAM) is initialized
|
||
|
|
on i5/OS using
|
||
|
|
the Initialize Optical (INZOPT) CL command. WORM media must use media format
|
||
|
|
HPOFS. DVD-RAM media must use media format UDF. Erasable media may use either
|
||
|
|
high performance optical filing system (HPOFS) or universal disk format (UDF)
|
||
|
|
depending on the requirements of the user. You can specify the format by using
|
||
|
|
the MEDFMT keyword on the INZOPT command. The following topic provide information
|
||
|
|
about the different media formats and a comparison so users of erasable media
|
||
|
|
can select the media format that best meets their requirements.</p>

This industry standard media format was originally designed to specify the volume and file structures of compact-disk read-only memory (CD-ROM) optical disks, and is a read-only media format.</li>

<li class="ulchildlink"><strong><a href="rzam4highperfofs.htm">High Performance Optical File System</a></strong><br />

High performance optical file system (HPOFS) is an IBM-developed

media format architecture available to use when initializing optical media

on the i5/OS.</li>

and some of the restrictions for the ISO 9660, High Performance Optical File
