Hitachi-LG Data Storage

Hitachi-LG Data Storage 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 Hitachi-LG Data Storage rather than just read about it. In short: Hitachi-LG Data Storage (HLDS, HL-DT-ST or H-L Data Storage), a joint venture between Hitachi, Ltd. and LG Electronics, is a manufacturer of DVD and Blu-ray optical disc drives for desktop computers and laptops. History Founded in late 2000, the company began operation in January 2001 and shipped its first product that summer.

Key takeaways

Hitachi-LG Data Storage 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 Hitachi-LG Data Storage to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hitachi-LG Data Storage from memory before moving on to harder problems.

Reference excerpt

History Founded in late 2000, the company began operation in January 2001 and shipped its first product that summer. In 2006, HLDS began developing Blu-ray Disc drives. The company claims that it has led the disk drive industry in market share since its founding, with a 20% share for fiscal year 2001, 29% for fiscal year 2012, and 60% for fiscal year 2016. In 2011, Hitachi and LG pleaded guilty to price fixing, and were fined USD21.1M.

Worked examples

Example 1 — a first encounter with Hitachi-LG Data Storage

Start with the simplest possible case. Write down what Hitachi-LG Data Storage 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 Hitachi-LG Data Storage 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 Hitachi-LG Data Storage 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 Hitachi-LG Data Storage

In research: Hitachi-LG Data Storage 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 Hitachi-LG Data Storage 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: Hitachi-LG Data Storage is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer companies established in 2000, Computer storage companies, Electronics companies of Japan, so understanding it makes those chapters shorter.
In everyday life: Look for Hitachi-LG Data Storage 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.
