JustLink effectively performs when writing data directly from CD-ROM, writing data at high speed and when other operations are being performed during writing. JustLink also makes trouble-free data writing via network possible. The link section from Ricoh JustLink , being extremely small at less than 2 m, doesn't affect reading quality. This is actually why this technology has been called 'JustLink ' which has the scope and flexibility to cope with whatever writing speed. Whereas data is recorded to HDDs and MOs uses physically short block with breaks in between the blocks, CDs are recorded so that there are no breaks in the data from beginning to end.
Data has to be written in one go since data is written to CDs as an essentially continuous line.
Even though CDs are said to be very resistant to dust and scratches, if there is a gap in the data it theoretically means that the data is lost, and will cause a reading error in any CD player or CD-ROM drive. If for some reason, the data being sent from the computer to the drive is late when writing takes place, writing is temporarily stopped when the data runs out, thus causing an error. This is called buffer underrun error. Once you get a buffer underrun error on your CD, the CD can no longer be read and in most cases it renders the CD useless. In contrast to the press molded music CD or CD-ROM format, buffer underrun errors do not occur with the original packet write system developed for recording with personal computers because data is divided into packets.
