[. . . ] Differs from the CD-R DAO method because the lead-in, data area and lead-out areas are all written sequentially. Incremental Recording (IR) ­ A DVD writing process that is similiar to the Session at Once (SAO) CD-R writing method; files may be added directly to the DVD-R disc one recording at a time, instead of recording the files to a hard drive before writing the disc. The minimum recorded size, though, must be at least 32KB (even if the file to be recorded is smaller than that), and capacities and write speeds are decreased due to the overhead of combined lead-in/out areas and data. Also, the disc must be finalized before it may be played back by a drive other than the drive recording the disc. Multi-Border Recording (MBR) ­ A DVD writing process that is very similiar to IR, MBR allows you to make an IR disc and then play the disc back on a device that recognizes this type of recording method. MBR creates a very short boundary zone around a recording session so a compatible player or DVD-ROM drive does not attempt to play beyond the border of the recorded area, instead allowing the unfinalized disc to be read by a player that supports this recording method. LaCie Slim DVD±RW Drive User's Manual USB 2. 0 Using Your laCie Drive page 20 Restricted Overwriting (RO) ­ A DVD writing process that only applies to Slim DVD±RW discs. With this method, if a disc has already been written to, new data segments can be randomly inserted anywhere within the recorded boundary. New data, however, can only be added to an area of the disc that has already been recorded over and from the point where the last session was stopped. Session at Once (SAO) ­ A DVD writing process which is similar to DAO, where all of the information is written in one session, but SAO allows for the ability to begin another session and record at a later time. This mode allows for greater control of the recording process than Packet Writing (PW) or TAO, and more disc space can be utilized because there is no need for gaps between tracks. Packet Writing (PW) ­ A writing process that is very useful for data backup. Buffer underrun* is impossible in this mode, because the data is written in "packets" of a few KBs. 3. 6. 2. CD Writing Methods Disc at Once (DAO) ­ A CD writing process in which the entire CD is recorded in one session, and data cannot be added after the recording is finished. This mode allows for the most control of the recording process for audio CDs because the gap between tracks can be set and the maximum capacity of the CD can be utilized. Packet Writing (PW) ­ A CD writing process that is very useful for data backup, but cannot be used to write audio CDs. Buffer underrun* is impossible in this mode, because the data is written in "packets" of a few KBs. Session at Once (SAO) ­ A CD writing process which is similar to DAO, where all of the information is written in one session, but SAO allows for the ability to begin another session and record at a later time. This mode allows for greater control of the recording process than PW or TAO, and more disc space can be utilized because there is no need for gaps between tracks. Track at Once (TAO) ­ A CD writing process where data is added one track at a time, and the data can be added at a later time. The CD being written to, though, can only be read in the CD rewritable drive that is recording it until the disc is finalized (meaning that no more data can be added). There is also a gap of 2 seconds added between tracks, which will be heard as noise in some audio players. recording of a disc is a system-intensive application, and the rewritable drive needs a constant stream of data. A buffer underrun occurs when the stream of data to the rewritable drive is not fast enough to keep the rewritable drive's buffer full, causing the an error in the recording process. [. . . ] This function prevents the entire chain of peripherals from freezing up if one of them is not working properly or is down. Important Note: Avoid using USB connectors found on certain peripherals such as keyboards. These are passive (or pass-through) connectors that lead to power loss and unstable operation. Important Note: Only use USB cables shorter than 5 meters (approximately 15 feet). [. . . ]
