What Should I Consider When Buying a DVD Recorder?

The English name of DVD is "Digital Versatile Disc", which is the successor of CD / LD / VCD. It only took more than a year from the initial specification to the introduction of the first DVD prototype in early 1996, which is a recognized next-generation standard storage technology.

Speaking of the development process of DVD burners, we must not mention the birth of DVD and the establishment of standards. The birth of DVD and the establishment of standards are directly related to the rapid development of the entertainment industry. Its predecessors, CD discs and VCD discs, were born from this. Increasing demands from media giants have stimulated hardware manufacturers to develop new DVD discs.

Note: In the early 1990s, the U.S. Film Industry Advisory Board drafted a letter of wish on behalf of the seven major Hollywood film production companies, one of which was to require a standard length (135 minutes) to be recorded on a CD Video programs and require higher image and sound quality than LD (this requirement was made in mid-1990s and was formally determined in 1994). And at the time VCD's

Used when making different types of discs

1. Adjust the power.

If necessary, you can disassemble the optical drive, find the knob to adjust the laser emission power, and use a small flat-blade screwdriver to adjust the power several times until it can be burned. note! If no conditions, skip this step, next. Don't blindly fumble without authorization, or you will be at your own risk.

2. Clean the bald head.

Spend 10 yuan, go to the street video store to buy a "VCD cleaning disc", such as "Four Sea Audio and Video VCD Cleaning Disc", DVD-like clean. Use the low-level industrial alcohol that comes with the cleaning dish

DVD burner thermal issues

In order to save costs, many friends bought a computer with a low-quality case. The case has serious heat dissipation problems. Because the optical drive generates a large amount of heat when reading the engraved disk, the failure to burn in time or the disk cannot be read for a long time; On the other hand, the installation of the optical drive is incorrect. When using two optical drives, the two optical drives are firmly held together, which seriously affects the heat dissipation of the optical drive. The long-term working capacity causes poor heat dissipation of the optical drive and overheats the electronic board, which seriously affects the optical drive Life.

DVD burner cleaning issues

The internal cleaning of the case is not in place, and a large amount of dust covers the optical drive, which seriously affects the heat dissipation of the optical drive, resulting in poor heat dissipation of the optical drive and crashing.

DVD burner other issues

In addition to the above heat dissipation problems, some incorrect use can also cause unreadable and burning failures.

1. There are some problems with ACPI power management of some older motherboards. Sometimes soft decompression software cannot disable the screen saver, sleep state, etc., which causes the system to freeze when the system enters the power saving state.

2. Run many programs at the same time or even use soft decompression software to make the system resources too low and cause the system to crash.

3. Some VIA / SIS chipset motherboards have older or less sophisticated IDE drivers installed than these chipset. Causes the CD-ROM to freeze in DMA mode.

4. The surface of some discs is not flat, because every point on the ring under the same radius is not on the same plane, or every point on this radius is not on the same plane, causing the optical drive to read a certain Dead reads occur in sectors.

5. ACPI advanced power management issues: due to software bugs, and chipset characteristics, BIOS writing, STR and other issues in a certain system state, power use, trigger timing, etc. caused a baseless and unreasonable crash.

The solution is to install a clean operating system and disable ACPI before installation or disable all options related to the hard disk, monitor off, sleep, etc. in the power management of the operating system.
