General Electric has developed a holographic optical disk that uses thermoplastic material. Even simpler to manufacture than photosensitive resins, which are a mainstay in development today, the holographic optical disk has a capacity that puts today's DVDs to shame, loaded with a whopping five terabytes (one tera equals a trillion) of storage, 1,000 times more than current DVDs. With its massive memory expected to be used as a recording medium for long-running TV series, medical data and other applications, the first of the discs should go on sale starting from next year.

The holographic disc uses a unique thermoplastic material that responds to a laser. Through injection molding, a single layer is formed by being impressed onto the disk. For this reason, no compression of material occurs during recording that is normally seen on photosensitive resin disks. It is said that simply by making impressions through injection molding the manufacturing costs will be greatly reduced. "At the very least we're talking about a capacity of at least 200 - 300 GB (1 GB = 10 billion) and in theory it could store as much as 5 terabytes of information," said GE Global Research optics engineer Brian Lawrence.

1. The industry term for 射出成型 appears to be “injection molding”.
2. This is wordy. Since the photosensitive resin shrinks, it’s implied that there will be a change in volume. I think we can do without these words.

射出成型 : injection molding
押出し成型 : extrusion molding

Said to be the successor in next generation DVDs (capacity of 20 - 25 GB), holographic optical discs are bringing the use of photosensitive resins into the forefront of development. The viscous nature of photosensitive resins hardens when data is recorded onto the disk. To maintain the layered thickness of accumulated memory upon the disk, it's necessary to sandwich the layers between glass substrates.

1. the next-generation DVD → next-generation DVDs
2. has → have
3. 20 or 25 → 20 - 25
4. piled up to form a disc → piled up on the disc
5. Good verb usage here!

1. development mainstream
2. photopolymer ⇒ photosensitive

1. Great verb! One of my favorites. I love it!
2. Another great verb for the context!

○ 後継
replace や succeed (successor) がキーワードとなる。

Although GE hasn't calculated exactly how much of a saving their optical discs will generate, DVD makers can manufacture holographic optical discs inexpensively at their existing plants, thus saving them the need to build costly new facilities.

Holographic optical discs are expected to become commercially viable sometime around 2010.

saving（削減、節約）の動詞に generate が用いられる。

1. Excellent word choice!
2. Although the Japanese does use 「導入する」, “introduce isn’t the best word to use in this context. While a company may introduce new methods and manufacturing procedures, it wouldn’t “introduce” facilities. Really, I think all we need to say here is that DVD manufacturers don’t need new facilities. The most natural word that comes to mind is that manufactures don’t need to “build” new facilities, but it doesn’t truly say that in the Japanese. Perhaps we can discuss this in class.
3. will begin around 2010

1. Yet の位置を変える。…has not yet estimated…
2. 同じ文の中で “cost” という語を繰り返し使わないように表現を変える工夫をする。prospective cost reduction → potential savings
3. カンマを削除。
4. It seems that のような表現は「かもしれないし、そうではないかもしれない」という弱いイメージを与えるので削除。This weakens the sentence plus it’s wordy.

1. photopolymer ⇒ photosensitive
2. according to xxx のところは前に持ってきたほうがよい。
3. “did not provide” というときは気をつける必要がある。日本語では「削減額を算定していないが」となっているので、ここは hasn’t determined cost savings, とするべきところ。did not provide だと「メディアが質問したけど、会社側は開示しなかった」ということになる。
