| The new blu-ray DVD disks introduced by the TDK | | | | Corporation’s commitment to the advanced |
| Corporation are the BD-R25, BD-R50, BD-RE25 and | | | | technology of optical disk has created the |
| BD-RE50. TDK BD-R25 and BD-R50 are | | | | world’s first high capacity Blu-ray DVD disks |
| “write-once” discs while the other two | | | | (25GB & 50GB) with capable recording speed of |
| BD-RE25 and BD-RE50 are the “rewritable” | | | | 2X. BD-R and BD-RE blu-ray disks from TDK provide |
| blu-ray disks. TDK (BD-R25) is single layered and | | | | greater facility along with large data storage |

| disk with more recording capacity of 50GB. BD-RE25 | | | | The other name for Blu-ray disks is “BD disk” |
| is dual layered, single sided blu-ray disk having 25GB | | | | which is the optical disk format’s next |
| recording capacity. BD-RE50 is also dual layered, single | | | | generation. This disk format was joint introduction by |

| Initially the blu-ray disks used a protected cartridge | | | | Mitsubishi, Pioneer, LG, Panasonic, Thomson, Sony, |
| but now TDK introduced the technology of | | | | TDK, Philips, Sharp and Samsung). The main purpose |
| DURABLES-2 (hard coating) in both the Blu-ray DVD | | | | for developing this DVD disk format was to enable |
| disks of BD-R & BD-RE. So, a recording surface | | | | the HD video’s rewriting, playback and recording |
| is achieved that is very highly resistant to dirt, | | | | and the ability to hold more volume of data. |
