System Description
In the image below an overview is presented of the system-functions of LabelTag. The PC host application controls the data location of the regular user data, including the structure of the file system. In the host application the user label input is transformed into a bit-map representation. The host sends print commands with the pixel information of the image to the drive. The drive interface, records the regular data, including lead in, session intros and closures, and finally lead out. The drive Interface (IF) part takes care of the interpretation of the pixel information and location of the image on the disc. The drive Servo part finally records the pixel information on the correct location including the encoded line numbering. The drive Servo part controls the record power, motor frequency, pixel frequency and channel bit frequency.

Famous quotes containing the words system and/or description:
“I confidently predict the collapse of capitalism and the beginning of history. Something will go wrong in the machinery that converts money into money, the banking system will collapse totally, and we will be left having to barter to stay alive. Those who can dig in their garden will have a better chance than the rest. I’ll be all right; I’ve got a few veg.”
—Margaret Drabble (b. 1939)
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
