Digital encoded audio & video information is stored on disks in form of pits. These pits are spiral grooves. The pits on the DVD disk have to be more closely packed and smaller in size to store more information. The reading laser has to be more precise in order to read data from the smaller pits. DVD media uses red-laser while blue-laser is used in the new Blu-ray media disc format. This is how the Blu-ray got its name because of the blue laser. As the coming into being of Blu-ray, many famous electronics manufacturers have produced their own Blu-ray players, and as the coming into being of Blu-ray players, many software developers have developed their own Blu-ray rippers for those guys who have a Blu-ray ripper or Blu-ray converter but want to enjoy the high quality of Blu-ray.

The thickness of DVD and Blu-ray disk is the same. The thickness of both disks is 1.2 millimeters. The data recording procedure is different for both disk types. DVD disc has 2 polycarbonate layers and the thickness of each layer is 0.6 mm. The information which is to be recorded on DVD disk is sandwiched between these 2 layers.

... layer on top of the recorded information can lead to birefringence. In birefringence, the laser light is refracted into 2 separate beams by the substrate layer. Data cannot be read from the DVD disk if the laser light splits too wide. Disk tilt is another problem that is caused if the surface of DVD disc is not totally flat or it is not precisely perpendicular to the laser the light. The laser beam distorts due to disk tilt. Very involved manufacturing procedure is required in DVD disk to avoid these problematic issues.

These problems have been solved in the Blu-ray disk format. In Blu-ray disk format, the data is recorded on top of polycarbonate layer whose thickness is 1.1 mm. This technique of Blu-ray overcomes birefringence. So as a result the readability problems are avoided in the Blu-ray disk format. In Blu-ray disc format, the objective lens and the recording layer are very closer to each other.

This closeness to the objective lens virtually eliminates the disk tilt problem which enhances the performance. The outer side of Blu-ray media disk is protected by a hard coating because the recorded information is very closer to the blu-ray disk surface. This hard coating feature makes the Blu-ray media unique, robust, efficient and more advantageous. The hard coating layer protects the Blu-ray disk surface from fingerprints and scratches. Therefore, the Blu-ray media disc is able to store information for longer time periods. Blu-ray media format is more reliable and robust.

But you may get puzzled that what to do if I want to enjoy Blu-ray disks on-the-go, for instance, on iPod, should I always bring a Blu-ray player? If you like, you can just choose a Blu-ray ripper, such as a Blu-ray to iPod ripper or Blu-ray to iPhone ripper, then rip and convert your Blu-ray disks to your PC and portable devices. Well, it is all up to you. Hope you can enjoy your Blu-ray life.
