The main focus of this product dissection was to fully disassemble a DVD-drive typical of [[optical drives]] used today for reading the data on the ubiquitous [[digital video disc]]. This particular device is intended to fit in the 5.25" drive bay of modern desktop computer towers. The procedure was to incorporate a complete product dissection including careful disassembly, component study, and  reassembly. The initial phase consisted of a complete tear-down of the product and photo-documentation. Subassemblies were numbered and placed in separate containers for later identification and ease of reassembly. Each component and subassembly was studied in order to better understand its function within the unit, and how it interacted with other components in order to perform the same overall function. Once inside, the intricacies and capabilities of modern electronics can be fully realized. The product itself is able to load a DVD disc into the tray, read it through the use of a [[laser]], convert the data into a signal readable by the computer in a package not much larger than the disc itself. After documenting a few crucial components in a 3-D CAD program the components were assembled back together. The process was straightforward and easy using only a small screwdriver and basic disassembly skills can completely remove almost all necessary components to study the product. As this was a base-model widely available device, and most certainly not intended for infinite life use, some of the components were not designed to withstand the forces necessary to disassemble it. These include many small plastic pieces and a small rubber belt that was missing upon delivery of the item.

Executive Summary

The main focus of this product dissection was to fully disassemble a DVD-drive typical of optical drives used today for reading the data on the ubiquitous digital video disc. This particular device is intended to fit in the 5.25" drive bay of modern desktop computer towers. The procedure was to incorporate a complete product dissection including careful disassembly, component study, and reassembly. The initial phase consisted of a complete tear-down of the product and photo-documentation. Subassemblies were numbered and placed in separate containers for later identification and ease of reassembly. Each component and subassembly was studied in order to better understand its function within the unit, and how it interacted with other components in order to perform the same overall function. Once inside, the intricacies and capabilities of modern electronics can be fully realized. The product itself is able to load a DVD disc into the tray, read it through the use of a laser, convert the data into a signal readable by the computer in a package not much larger than the disc itself. After documenting a few crucial components in a 3-D CAD program the components were assembled back together. The process was straightforward and easy using only a small screwdriver and basic disassembly skills can completely remove almost all necessary components to study the product. As this was a base-model widely available device, and most certainly not intended for infinite life use, some of the components were not designed to withstand the forces necessary to disassemble it.
