Difference Between DVD5 and DVD9 (With Table)

There are several versions of DVD discs that are available in the market. Each of them has a different storage capacity. It is quite discernible from their names that DVD5 and DVD9 are two versions of DVD discs. They have many distinguishable features including their nature, price, video quality, formats and much more. 

DVD5 vs DVD9

The difference between DVD5 and DVD9 is that DVD5 is a single-sided disc that was released way before DVD9. It is single-layered as it can hold only one layer of information. On the other hand, DVD9 is an advanced and upgraded version of the former. It is single-sided as well but has the quality of being double-layered.

DVD5 is an old version of DVD discs that can hold up to 4.7 GB of data. It is named so because it can hold nearly 5 GB of data. The disc can either be used as a commercially produced disc that contains movies and software, or as a writable disc. However, it is single-sided and single-layered.

DVD9 is a new and advanced version of DVD discs that can hold up to 8.5 GB of data. It is also called DVD-R9, DVD-R DL and DVD+R9. This disc is mostly used for commercial purposes because of how much data it can hold. DVD9 is single-sided like DVD5; however, it contains two layers of information, which is why people call it double layered.

What is DVD5?

DVD5 is an old version of DVD discs that are capable of holding 4.7 gigabytes of data. It is a standard single-sided and single-layered disc. Essentially, it can be compared with a CD as its underside has bumps and pits on it. These represent binary 0s and 1s that are read by a laser. However, unlike CDs, the pits and bumps on a DVD are placed closer to each other. This allows the disc to hold more data and information.

The disc is made up of polycarbonate plastic and has an aluminium reflective layer on it. On the top side, a label is silk-screened onto the surface. While commercial discs are made using this architectural design, recordable discs are drastically different. Instead of pits and bumps, the colour of the dye is used to store data. This dye is lasered onto the disc as well.

DVD5 is generally used to write data. The versions that can do this task include DVD-R, DVD+R and DVD-RW. They generally have a life span of 30 years; however, they are also good for storing movies and software. The disc plays videos in standard quality and can play for up to 120 to 133 minutes. These discs are even reusable and rewritable.

What is DVD9?

DVD9 is a newer and advanced version of DVD discs that are capable of holding up to 8.5 gigabytes of data. It is single-sided like DVD5 but is dual-layered. Many films and entertainment media released on DVDs use this version of the disc. This is because it can hold almost twice the amount of data than DVD5. It offers more space for trailers and deleted scenes. It even uses less compression which accounts for high-quality videos.

The disc can play up to 240 minutes of video. This accounts for its higher price as compared to DVD5. Regardless, the disc cannot be reused or rewritten. The disc does not have pits and bumps but uses dye laser technology to store information.

A limitation of this disc is that it has several compatibility issues with DVD-ROM. A useful solution provided by its makers is to record the two layers of the disc equally. However, this is a contradiction as the nature of the two layers is sequential.

For this, the makers came up with a technology called Layer Jump Recording. Layer Jump recording allows a user to incrementally record small sections of each layer. This drives away all compatibility issues with DVD-ROM.
