RSJ ANNOUNCES THE RSJ CD WRITER FILE SYSTEM
January 1994

We've just finished an OS/2 file system which allows writing to Writable CDs.
This file system has the following features:

- simply access writable CDs via an OS/2 drive letter
- to create custom CDs, just use COPY, XCOPY, the WPS or whatever tool you
  prefer
- ISO9660 compliant
- support for Kodak PCD Writer 200/225 and Phillips CDD 521, support for
  additional drives planned in future versions
- multi-session capability
- open and work with any session on the CD (including previously recorded
  sessions)

General Description
-------------------

The RSJ CD Writer File System provides transparent access to Writable CDs
under OS/2. The product-specific advantages in comparison to conventional
mastering software are:

- Writable CDs are accessed like simple diskettes; all OS/2 programs
  designed to manage files on dikettes and hard drives can be used to
  create CDs.
- no extra hard disk required to temporarily store an image of the CD
- no extra SCSI host adapter required
- runs with all SCSI host adapters supported by OS/2, providing they work
  together with the CD Recorder.
- the CD Recorder can be used as a CD-ROM drive as well

Hardware Requirements
---------------------

- IBM compatible PC with an i386 CPU or better
- SCSI host adapter with OS/2 support
- 16MB RAM
- CD Recorder

Software Requirements
---------------------

- IBM OS/2 Version 2.1 or better

Supported CD Recorders
----------------------

- Kodak PCD Writer 200
- Kodak PCD Writer 225
- Philips CDD521
- Philips CDD522

Other recorders (especially Yamaha) will be supported in the
near future.

Supported CDs
-------------

- CD-ROM recorded according to ISO9660 (read only)
- Writable CD (read/write)
- all CD sizes supported by the CD Recorder

File System Details
-------------------

- compatible to ISO9660 with extensions to support Multisession CDs
- the CD maps to an OS/2 drive letter which can be accessed like a
  huge diskette via standard OS/2 commands and programs
- OS/2 disk management commands (such as FORMAT, CHKDSK, ...) are
  supported
- CDs are written in CD-ROM mode (Mode 1, Form 1 sectors). This
  allows using even old CD-ROM drives to read at least the first session of the CD. XA support is not required , reading multiple sessions, however, requires a multi-session capable CD-ROM drive.
- previously recorded sessions can be accessed and even modified
- CDs can be "sealed", which can be compared to a write-protected diskette.
  The write protection can be removed at any time

Limitations
-----------

- no support for extended attributes or long file names. Otherwise,
  the CD might be incompatible to conventional CD-ROM software
- no multimedia support (play/record music tracks, ...). Multimedia
  support is planned in future versions.
- no WPS integration (special drive object, ...). WPS integration
  is planned in futures versions.
