But still you can definitely find many collections of DVDs in the homes of all of us.
Where CDs have less storage, DVDs have 3 to 4 times more storage than this. These DVD drives already come in today’s laptops and computers, using which we can play any DVD or CD. Whereas DVDs come according to an external device, which we can connect with our Television. Many people have a lot of questions about the DVD, so today I thought why should you answer all the questions of your people through this article what is the meaning of DVD. Then let’s start without delay.
What is DVD?
The full form of DVD is “Digital Video Disc” or “Digital Versatile Disc,” it depends on what you are asking or what you are reading. The size of DVDs is exactly the same as the size of CDs and if there is no label in the disc then it can be very difficult to tell the difference between these two.
Laptops that run Windows can easily play DVDs; The software and permissions required to run it vary from versions of one operating system to the other. For example, Windows 7 has built-in DVD compatibility, while other windows versions have to use additional software to run it and pay somewhere to upgrade it.
What is DVD Writer and its types
Optical disc drives are used to play CDs and DVDs which come in-built with the computer. There are mainly two types of drives:
Readers – They only read data from discs.
Writers – also called recorders or burners – help to copy data into discs.
Most drives are reader-only, but writers are also available in combination with readers. So if you have to buy a CD or DVD, then it is very important to know about it.
How much space does CD and DVD have?
You can store up to 700 megabytes of data or 80 minutes of music in a CD. While you can store up to 4.7 gigabytes of data in a standard, single layer blank DVD, you can store about 7 times more information which is 2 hours of high-resolution video.
Both forms of DVDs: single and double-layer forms
Double layer discs are also called dual layer. It is often used for all DVD movie discs. They hold data of about 8.5 gigabytes and add additional information such as multi-language soundtracks, extra scenes and other “bonus” material to the rest of the extra space.
Apart from this, due to the large amount of storage space, it allows DVDs to store higher quality audio and video content, compared to earlier older video storage media such as VHS tapes. Apart from this, DVDs are more versatile than VHS tapes, as it does not require much rewind.
What are all DVD Formats?
What are the different formats like DVD-R, DVD + R, DVD-RW, DVD + RW, DVD-ROM, and DVD-RAMDVD-RAM —
All these Formats are related to each other, but still they are somewhat different from each other. Like DVD-R (pronounced “DVD minus R” or “DVD dash R”) and DVD + R (pronounced “DVD Plus R”), they can only be written once. That is, there are recordable formats – which means that they are used to record data only once and that data is stored permanently in the disc.
These formats work in the same way but are not always compatible with each other. For example, DVD-R discs work on Apple Mac computers, but DVD + R discs do not work. It is similar to some recent DVD recorders, created by companies such as Panasonic, Pioneer, and Toshiba, which can playback DVD + R and DVD-R discs, but only one type. You can record new contents that are in a particular format, either DVD-R or DVD + R, but not both.
DVD-RW and DVD + RW means you can re-record those discs. Just like recordable CDs. The full form of “RW” is “Re-writable.”
DVD-RAM is a format that is supported by only a few companies in which Panasonic and Toshiba are the main ones, and these are also re-writable DVDs that are mostly used for recording in computers and some Also in home DVD recorders. These formats are not universally supported, which means that you cannot play them on most DVD players and computers.
A DVD-ROM is a format that is mostly used to store large software applications. It is similar to a CD ROM but its capacity is very high. The data in this DVD ROM can be written only once and cannot be re-written over it.
What is the difference between a CD writer and a DVD writer?
The simple answer is that two different types of lasers heads are used in these two; One is for DVD and the other for CDROM, where CDROM laser has a wide beam and its maximum storage is around 700MB, whereas DVD has very high capacity in narrow beam only.
If you want to play a DVD in your computer but you do not know how to play it, then you must read the steps given below.
Let’s know how to play your CD or DVD in a computer by following the step-by-step instructions.
Step 1: First you have to see which type of disc drive (s) you have.
PCs often have two drives: a DVD reader at the top, and a combined DVD / CD reader / writer at the bottom. Both of these are actual drawer-like trays, in which a DVD or CD is filled and then the tray is closed.
There is a combined DVD / CD reader / writer in the laptop which is located on the side of the keyboard. All-in-one and touch-screen computers have a drive on one side, which is immediately behind the screen.
Step 2: Now you have to find out how to open the disc drive. This is normally done by pushing the button.
In PC, ‘open’ (or ‘eject’) is under the buttons tray.
In the laptop it is in the button tray itself.
You have to press button to open. If the tray is motorized, then it will open completely. If it is not, then it will open slightly and then you have to gently pull it out.
Step 3: After this you have to fill the disc in the computer’s disc drive:
This tray is ‘indented’ so that the disc sits easily.
The one that glows on the side is kept on the bottom, because it contains data only. After that he has to push slowly.
Step 4: If the tray is motorized, then it will automatically stop when you press that eject button again. Otherwise, it will go inside as soon as a little push.
Step 5: After this, an icon will appear on the CD / DVD which will appear in the computer desktop. At the same time, you will also see a menu of what you want to do with that disc. You can play the data if you want.
Step 6: If you have to disc eject, then you have to first turn off the software that you are using to play the CD / DVD. Then right click on the CD / DVD icon, which shows the option to eject it. Clicking this will eject your CD.
Caution: – Never, while moving the CD / DVD, do not remove it directly from the tray, it can cause damage to your computer along with the CD / DVD.
