[. . . ] · Handle discs only by the outer and inner edges. ·Never write with a ballpoint on the surface of the disc. ·Do not store a disc in places with high temperature and humidity. Do not place the disc under direct sunlight. · Store discs in their cases to prevent dust contamination, scratches, bending and other damages. · When a disc becomes dirty, clean it with a cleaning cloth. Do not use solvents such as benzine, thinner, commercially available cleaners, or anti-static fluids. Using fluids of these types may damage the disc. · Empty discs are separately available through your dealer. · To get an optimal temperature controle, you should close your PC after installing the drive in this way the central fan will help cooling your drive and keep performance according specification. · Unloading a disc after recording might take some time, because the drive has to update the TOC before the disc can be ejected. 13 01_LAYOUT_GB 22-11-2000 09:21 Pagina 14 CDRW ADDITIONAL INFO (CONT. ) ENGLISH Technical data PERFORMANCE Capacity 120mm disc (74/80mm Audio) 80mm disc Access time average 1/3 data(1) Access time max(1) Data-transfer-rate (recording) speed, mode 2 data) Data-transfer-rate (read only) Max. burst rate Interface Form factor Data integrity from drive, assuming new discs Data buffer Disc loading NOTE: THIS 650 Mbytes/700 Mbytes 200 Mbytes 120 msec. 1, 4 MB/sec sustained (8x Up to 5600 Kbytes/sec (32 speed, mode 2 data) > 2, 5 Mbytes/sec _ (Enhanced) IDE 5, 25" Half Height 10-12 2Mb Tray (motorised) DRIVE HAS AN ANGULAR VELOCITY 32 READ SPEED MODE, THIS MEANS THAT THE MOMENTARY SPEED WIL INCREASE FROM OF THE DISC OF 21 TIMES SPEED AT THE INNER DIAMETER (IE.

C-tick (1) Specifications for the "under pressure" case (incomming air flow through the front bezel) : A flow of at least 2 l/sec. of air at maximum 40 °, must be realised. This will be achieved by realising at least -180 Pascal of pressure difference between inside the apparatus and outside. Specifications for the "over pressure" case (outgoing air flow through the front bezel) : A flow of at least 2 l/sec. of air at maximum 40 °, must be realised. This will be achieved by realising at least +180 Pascal of pressure difference between inside the apparatus and outside. Additionally, the measured temperature of the bottom plate of the drive must not exceed 50 ° C. Remark: under an environmental temperature of the drive between 5 ° to 30 ° C no airflow is necessary. 15 01_LAYOUT_GB 22-11-2000 09:21 Pagina 16 CDRW ADDITIONAL INFO (CONT. ) ENGLISH Audio performance · Audio specification for line out: On pressed CD Output Voltage Unbalance Output Impedance Amplitude Linearity S/N-ratio Total Harmonic Distortion + Noise Outband attenuation Channel separation Muting level during random access 1 V rms max 0. 25 dB 470 Ohm 1. 5 dB (20 Hz - 20 kHz) 81 dB (84 dB A-wtg) 65 dB (1kHz) min. 70 dB (BW = 20 kHz) On recordable CD 1 V rms max 0. 25 dB 470 Ohm 2. 5 dB (20 Hz - 16 kHz) 80 dB (82 dB A-wtg) 55 dB (1kHz) min. [. . . ] · Fixation is the process of writing the lead-in and lead-out information to the disc. This process finishes a writing session and creates a table of contents. · Fixation is required for a CD-ROM or CD-Audio player to play the disc. Discs which are "fixated for append" can have additional sessions recorded, with their own session lead-in and lead-out, creating a multisession disc. [. . . ]
