Nowadays, with the popularity of high definition TVs (HDTVs), readers and Blu-ray discs are bringing another wave of innovation in the home entertainment industry. Blu-ray technology is considered to be a replacement for HDD and tape, so what features make it better?
Examples of Blu-ray technology
- Blu-ray, HDD and tape.
- Blu-ray technology
Blu-ray is an optical disc format that is used to store high definition video as well as games. These discs are new generation DVDs technology that provides Full HD picture quality and because they are similar to standard DVDs, these discs are very easy to use. Perhaps most importantly, the menus are the same in both formats, and the Blu-ray player can play back your entire library of silver discs whether they are CDs or DVDs.
HDD (Hard Disk Drive) is a traditional hard drive; data is stored on the surface of platters made of aluminum, glass or ceramic coated with magnetic material. The center of the drive is a spindle motor, to read / write data the manufacturers have used the actuator in combination with the actuator arm Slider and Read / Write Heads and these are controlled by a small set of microchips, which control the reader correctly in place on the platters when the disc is spinning at speed. HDDs technology is also “non-volatile” like solid-state drives, but they have a completely different structure. The data structure of HDD is divided into Track, Sector, and Cluster.
Magnetic tape is the technology by which magnetism is stored to store signals, which can then be reproduced through electronic systems. Tape is used in recording, recording and recording digital data. The type of calibrating tape that is defined and fixed to a fixed box is called a cassette, with a tape deck and a shaft, the smaller type used in recording, the larger type used for recording, and both are used in recordings.. Magnetic tape created a revolution in recording and sounding back in the 1930s. However since 1997 magnetic tape has become obsolete and has been replaced by other means of recording optical discs, and since 2010 flash memory.
- Blu-ray technology is better than HDD and tape.
- Better image quality.
Blu-ray technology produce better picture and image quality, it is even better than satellites broadcast. The resolution quality could go up to full HD.
- Better audio quality.
Blu-ray has brought home the first round of home audio capabilities and the feel of DVDs to a new level. Its high-capacity format allows for higher sound depth and better support for additional speakers.
- Unlimited on the disc.
Newer Blu-ray players connect to the internet to bypass the content restrictions of Blu-ray Discs and support for online video-on-demand applications such as LOVEFiLM. This technology support applications depends on the type of light and the form of a Blu-ray player, but applications are quickly becoming a standard feature that can bring great convenience and allow for content selection easily.
When HDD and tape were born, they were considered to be a big change in data storage. However, since Blu-ray technology appeared, it totally replaced HDD and tape, their better advantages compared with HDD and tape cannot be denied.
