Optiarc

Optiarc is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Optiarc rather than just read about it. In short: Optiarc is a brand of optical disc drives and solid-state drives. It is owned by a US-based Vinpower Digital, Inc.

Key takeaways

Optiarc belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Optiarc to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Optiarc from memory before moving on to harder problems.

Reference excerpt

Optiarc is a brand of optical disc drives and solid-state drives. It is owned by a US-based Vinpower Digital, Inc. Initially Optiarc was established on April 3, 2006 as a joint venture between Sony (55% shares) and NEC (45% shares). The company, named Sony NEC Optiarc, focused on manufacturing optical disk drives primarily for the OEM desktop and notebook PC markets. On September 11, 2008, it was announced that Sony would take over NEC's 45% share, making Optiarc a wholly owned subsidiary of Sony, to be called Sony Optiarc. This took effect on December 5, 2008 In March 2013, Sony closed its Optiarc optical disc drive division, laying off about 400 employees globally. In 2017, an American company, Vinpower Digital, whose main business is manufacturing optical disc and other media duplicators for the commercial market, acquired the rights to the Optiarc brand and product line. The brand PioData is also owned by Vinpower Digital.

Products Products were both DVD+/-R(W) and BD-ROM drives. Among other things, Sony Optiarc supplied the Blu-ray drives for the Sony PlayStation 3. The naming scheme for the drives is as follows: DDU stands for DVD-ROM, AD stands for DVD-RW, BR for BD-ROM and BC for BD Combo. A combo drive is a drive that only supports the newer format in reading and the predecessor in writing. The three digits that follow indicate the generation, the design (5.25" or slimline) and the speed class. The digit after that the equipment variant and the appended letter the interface. An AD-7243S is a 5.25" DVD-RW Drive with 24x speed when writing to DVD-R and DVD+R blanks. It also supports Labelflash. For Lightscribe, a "1" would be in the fourth position. The "S" indicates SATA. An “A” stands for PATA. However, all PATA Optiarc drives are now discontinued.

Worked examples

Example 1 — a first encounter with Optiarc

Start with the simplest possible case. Write down what Optiarc claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Optiarc before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Optiarc ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Optiarc

In research: Optiarc appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Optiarc in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Optiarc is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2017 mergers and acquisitions, Brand name products stubs, Computer storage companies, so understanding it makes those chapters shorter.
In everyday life: Look for Optiarc outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Optiarc in simple terms?

Optiarc is a brand of optical disc drives and solid-state drives. It is owned by a US-based Vinpower Digital, Inc.

Why does Optiarc matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Optiarc?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
