Blu-ray Features:

A Blu-ray Disc (BD) is a next generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of many leading consumer electronics, personal computer and media manufacturers. The format was developed to enable recording, rewriting and playback of High Definition (HD) video, as well as high capacity of data storage.

More information on Blu-ray can be found from our own article: Blu-ray vs. HD-DVD.

Blu-ray Format Type:

Similar to DVD-RAM, a Blu-ray disc can be formatted in the following types: UDF 1.50, UDF 2.00, UDF 2.50, UDF2.60, and FAT32.

Before using BD-R and BD-RE media for writing files on the disc, we must logically format the media. Once we have logically formatted BD-R or BD-RE disc, it can be use to write files just as you would do with a floppy disk, hard disk or DVD-RAM. In the illustration below we will use Panasonic UDF Formatter (DVDForm) version 5.1.1.0 to format a BD-RE disc.

DVDForm offers several format types for BD-RE disc

It took 37 seconds to quick format a BD-RE disc in FAT32

BD-RE Single Layer discs formatted with FAT32

Now we will attempt to do a quick format on a BD-RE media with format type UDF2.5.

Let’s move along to check out the LG GGW-H20L’ reading and writing performance

Reading and Playability of commercial BD-ROM SL/DL: 

Here we will look at how the LG GGW-H20L performs when reading and playing back commercial BD-ROM discs.

BD-ROM SL

The LG GGW-H20L read our SL BD-ROM at a speed of 4.78X.

BD-ROM DL

Reading of BD-ROM DL is done at 4X.

Both discs also play back perfectly on our test system using PowerDVD Ultra which is included in the software package from CyberLink.

Now we well move along and take a look at the writing abilities for this drive…….

BD-R and BD-R DL Writing Speed and Quality:

To demonstrate burning data on a Blu-ray disc, we will use Nero CD-DVD Speed with Create Disc feature. We will use ImgBurn when we burn Hi-Def video. The ScanDisc test is performed in the LG GGW-H20L drive to check if there is any issue with the burned disc.

Now let us take a look how the drive performs on various BD-R media:

Summary:

As we can see, the LG GGW-H20L drive supports writing our Verbatim and Panasonic BD-R 2x media at 6x giving a write time of about 22 minutes. It also reads and writes BD-R/RE single layer discs without any problem. ScanDisc tests show no problem at all.

Blu-ray playback test

Since we burned 4 of our test discs with HD Video, we tested them with our stand-alone BD player; here is a table to show those results:

The drive and software played back our High Definition Blu-ray movies without any issues.
