caption_attribution_description: English: data format to send pixels to the drive for LabelTag
context_page_description: LabelTag can create a circular label on the data side of any DVD+R, DVD-R, or CD-R disc containing basic information visible to the eye. When burning the data, the label is printed directly behind that data in the same recording session, and on normal recording speed on the same recording layer side. LabelTag works on any disc and does not require a special disc like LightScribe. Currently, LabelTag is an exclusive technology of Lite-On for its DVD writer drives.
  An older alternative disc labeling technique was DiscT@2. To record the label on the opposite or back side of the disc by the drive itself LightScribe and LabelFlash are current standards. Besides that, printing using an inkjet printer is currently widely used.
context_section_description: For LabelTag no new commands are introduced; the changes are made to the already existing commands. Pixel data describing the pixels for one or more image lines is sent to the drive via the WRITE12 SCSI Write Commands. The line width and number of pixels in each line are set in the LabelTag SCSI mode pages. The WRITE12 command is called TAGWRITE command to emphasize the dedicated LabelTag SCSI mode pages settings. After this command the image data is located in the drive buffer. The drive starts writing after the buffer is full or a SYNCHRONIZE CACHE command is sent.
