Write operation
The REC/PLAY disc tray (CD-R/RW drive) is composed of the mechanism unit (HXL-3BSPA) and the board
ass'y (HQA-030A).
Therefore, in case of a write failure, check the following points first before proceeding to the next step.
The trouble is not due to the disc defect.
The FPC cable connecting the mechanism unit and the board ass'y is not disconnected or unplugged.
1. Symptoms, which may be due to a defect in the mechanism unit (HXL-3BSPA)
(1) There is no trace of writing on the CD-R/RW disc.

(5) Either the CD-R or the CD-RW disc cannot be written onto.
(6) Disc cannot be recognized as a recordable CD-R/RW disc.
(7) Abnormal noise from the mechanism during disc rotation.
(8) Disc will not rotate.
(9) Disc rotation is unstable (the rotation speed increases suddenly).
2. Symptoms, which may be due to a defect in the board ass'y (HQA-030A)
