- I removed the four screws on the back panel and lifted off the casing to expose the internal components.
- The disc tray was stuck inside, which I suspect was one of the reasons for the device’s failure. I forcibly removed the tray from the housing.
- Next, I unscrewed the board connected to the charging port and separated it from the main logic board of the DVD Writer.
- I then removed the circuit board near the charging port, which seems to be responsible for charging functions. I detached the FFC/FPC cable (Flexible Flat Cable/Flexible Printed Circuit) connecting this board to the main DVD circuit board. The cable was plastic-like and difficult to remove, so I cut it in two.
- I took out the metal plate attached to the main structure of the DVD writer. This plate was used to secure the internal components and prevent them from moving. Some screws were difficult to remove, so I forcibly took them out.
- I removed the spring mechanism responsible for ejecting the DVD tray. It was jammed inside, but only required unscrewing one easily accessible screw.
- I removed a FFC/FPC cable, a long metallic strip used to connect circuit boards. Additionally, I removed some nearby PCB mounts or clips used to secure the circuit board.
- I detached the upper part of the spindle motor assembly, which is responsible for rotating the disc. I also removed the associated control PCB.
- Lastly, I removed the spindle motor and its mechanical components, which drive the disc’s rotation within the DVD Writer.（As shown in the figure below）

I find the internal structure of this device particularly intriguing because of its compact and portable size, which leads to a very tight arrangement of components. To maximize space efficiency, the spring mechanism is cleverly shaped to conform to the central structure.
