Portable DVD players are real lifesavers when it comes to long distance trips with kids in the back of the car. By the end of this article, you will have enough knowledge on What Is A Portable DVD Player And How It Works.

What Is A Portable DVD Player?

A portable DVD player is simply a battery-powered mobile device. It is a source of entertainment while one is on the go.

Today’s portable DVD players play files from SD cards or USB flash drives. In the present mobile world, tablets and smartphones have replaced portable DVD players; however the players are still popular in the market due to their affordable price.

How Portable DVD Players Work

A simple method to understand how a myportabledvd.com player works is to have a look at its earlier version, the record player.

When it comes to the record player, it is possible to see the needle recording the grooves in the vinyl. The DVD player employs similar technique except with extra benefits of the technology in the 21st century.

Laser Reads The Disc

The storage of the information on a DVD player is in divots in the plastic layers. It is the same to the grooves on a record player but is more accurate. From the outside a DVD appears like it is fully made of plastic, however, inside the plastic covering is an aluminum layer.

This is essential so that the laser in the machine can emit light via the plastic and reflect it to the lens on the opposite direction. The laser is extremely thin and accurate, unlike the ones used in a normal science lesson.

Inside a DVD player is a computer chip which employs a device known as the MPEG-2 decoder which converts the information from the lens into digital signals and audio, which is then displayed on your screen via audio and video cables.

The Motor Rotates The Disc

If the disc stays immobile in the DVD player, the laser cannot read the data as required. For that reason, the motor of the machine spins it, and the player decodes the data for the full movie by making spiral movements from the interior to the exterior part of the disc.

The speed the machine takes to decode the data depends on the type of the disc in the DVD player. If it is a “double layer” DVD, the moment the laser reaches the outer part of the disc, it reads extra tracks moving back to the center of the disc.

Device Measures Tracks

Besides, the DVD player has a machine that operates tracking, helping the laser to move inwards and outwards as required to remain in the right place on the disc.

This technique ensures the laser reads the right information at the right time. It also enables you to forward the movie by pressing the button “skip track” on your remote. The machine directs the laser where to go.

NOTE: Although we are all concerned about the scratches we see on the reflective sides of our DVDs, a significant amount of data the DVD player reads is deeply enclosed and near the label part of the disc.

For that reason, you can at times repair small scratches by polishing the disc or simply filling them, nonetheless, if you damage the label side, your disc is of no use anymore.

Conclusion

Portable DVD players help many people to deal with boredom, especially when taking long trips in a vehicle or an airplane. They are available at a pocket-friendly price, making them affordable for most individuals.

There a wide variety of portable DVD players in the market today, therefore buyers need to make the best choice by picking the model that suits their requirements. When purchasing a portable DVD, consider these four factors: battery life, connectivity, size and the overall price.
