Differences between DVD5, DVD9, DVD10 and DVD18
DVD is almost identical to a normal CD. The DVD, however, consists of two half-discs, which can hold movies, audio files, better than CD quality and computer data. Initially, users were simply popping the DVDs into players for watching movies. But there was a large scale evolution of DVD technology which led to the birth of multiple formats of DVDs. Users can now record, erase and re-record into DVDs just like they used to do with the compact discs. In this article, we will introduce main 4 different DVD types: DVD5, DVD9, DVD10 and DVD18 and their differences.
The DVD-5 is a single sampled, single-layer DVD at 4.7 GB of storage capacity. More specifically, it is only 4.37 GB.
The medium consists of two halves. Both halves are made of polycarbonate, which serves as a carrier material. At the one half of a recording layer made of aluminum is deposited and covered with a protective layer of polycarbonate.
The DVD 10 is a sampled double-sided, single-layer DVD with 9.4 GB of storage capacity.
The medium is composed of two halves. Both halves are made of polycarbonate, which serves as a carrier material. In a recording layer is deposited in each case, and sealed with a protective layer of polycarbonate.
To all data on the DVD 10, it must be turned, because the laser is in a DVD-ROM drive only on the bottom.
DVD-9 is a single sampled, double layer DVD with 8.5 GB of storage capacity.
The medium is composed of two halves. When halves which the carrier material of polycarbonate. On one half of a layer is vapor-deposited, which is usually made of aluminum. This recording layer is called Layer 0.
A second semi-permeable layer is deposited thereon. It is usually made of gold or a combination of silicon and carbon (SiC), or silicon and nitrogen (SiN). With another polycarbonate layer DVD-9 is sealed with a protective layer.
Data carrier layers on the DVD-9, the opaque and the transparent layer. By changing the focal length of the laser can be read alternately between the opaque and the transparent layer.
The DVD 18 is a sampled double-sided, double-layer DVD 17 GB of storage capacity.
The medium consists of two halves, each with 4 layers. The middle part is a thick layer of polycarbonate. It is the foundation for the other layers. On the polycarbonate has a thin layer of an opaque but reflecting material is applied (Layer 0). In a similarly thin transparent but semi-transparent film is applied. A protective layer of polycarbonate is the final for the DVD-18th.
The data carrier layers on the DVD-18, the opaque and the transparent layer. By changing the focal length of the laser can be read alternately between the opaque and the transparent layer. since the DVD-18 is a two-sided DVD is, it must be rotated when you want to access to all data.
The video or the game is burned onto the DVD and the disc will run on any device which is equipped with DVD-ROM. The DVD-ROMs and CDs are very similar in nature. To play the DVD videos on computer or tablets without DVD-ROM, you can use Brorsoft DVD Ripper(or Mac version) to convert DVD movies or games to streaming video format like MP4, WMV, MOV, FLV and so forth. If you want to burn videos to DVD but don't know which kind of DVD discs can be used to store your files, just have a look at the table below, which compares the differences between DVD5, DVD9, DVD10 and DVD18:
As you read this, you may have already received a comprehensive understanding about the differences between DVD disc like DVD5, DVD9, DVD10 and DVD18. Hope it can be useful to you for playing, copying and burning DVDs with ease.
