Key takeaways

  • Sony Multimedia CD-ROM Player 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 Sony Multimedia CD-ROM Player to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sony Multimedia CD-ROM Player from memory before moving on to harder problems.

Reference excerpt

The Sony Multimedia CD-ROM Player was a portable CD-ROM–based multimedia player produced by Sony and released in 1992. It was used to run reference software, such as electronic publications and encyclopedia. Before its release, both Sony representatives and the press referred to the device as the Sony Bookman; that name remained in use in later publications. The player was sold concurrently with Sony's Data Discman e-book players. Unlike those devices, the MMCD Player could read full-size 120-millimeter CD-ROM discs, including audio CDs. Software format, proprietary to the player, was one of several rich media CD formats released to the market during the early 1990s.

Overview The MMCD Player has a clamshell form factor with an LCD screen and a QWERTY keyboard, complete with a numeric keypad, four-way navigation pad, "yes" and "no" buttons and a set of function keys (F1 to F5). The keyboard is located on a top of an inner lid which covers a top-loading CD drive. Discs for the player used the CD-ROM XA sector format and a software format proprietary to the player. Software which the player supported was marked by the "MMCD Player Software" logo (not to be confused with MMCD, a high-density disc format proposal by Sony and Philips). Takashi Sugiyama, Sony Corporation of America's project manager, attributed the MMCD Player's lack of support for established CD-ROM XA–based multimedia formats to its sub-VGA display resolution and the lack of hard drive caching support.

Software Newsweek chose the Sony MMCD player as a pilot platform for Newsweek InterActive, a quarterly CD-ROM magazine initially published in March 1993. The magazine was later released on compact disks for IBM PC compatible computers. No more than "a few thousand of units" of the MMCD version had reportedly shipped by 1995. Titles by Compton's NewMedia (a CD-ROM publishing arm of Encyclopædia Britannica, Inc.) and Random House were also available, with some disks including software for both the MMCD Player and computer platforms such as DOS and Windows. Several companies marketed Sony MMCD Player–based kits to real estate brokers. Digital Data, a company based in Irving, Texas, adapted Austin multiple listing service data as a weekly CD-ROM publication in 1994. In 1995, San Diego–based Visual Display Marketing was pitching their MMCD Player–based product to real estate associations, with its owner Gary Ripsco describe the concept of publishing weekly or biweekly home listing discs. Microsoft announced support for the MMCD Player for their multimedia authoring tool, Multimedia Viewer, upon the player's introduction on September 16, 1992.

Reception The Sony MMCD player was introduced the same month as Kodak's Photo CD format and the Tandy VIS multimedia system. Multimedia & Videodisc Monitor described the interactive multimedia landscape as looking "chaotic" and stated that consumers and commercial end users "probably can't" figure out then-current format situation. PC Magazine noted that the introduction of multiple CD-ROM format compatibility logos, along with Sony's MMCD one, make shopping for multimedia titles "anything but simple" and go against the goal of Multimedia PC program. Later, PC Magazine advised anyone but corporate purchasers "with a driving need to do away with a paper" against buying the Sony MMCD player, criticizing its high price and the incompatibility with other multimedia formats. The Washington Post noted the player's ease of use, comparing it favorably to Walkman compact disk players, but criticized the device's speed and the resolution of its built-in screen. In a 2006 column, Michael Rogers, who was an editor of the Newsweek Interactive division in the 1990s, said the Sony MMCD player was "far ahead of its time" but "slow as molasses." He noted that, as the device loaded the Newsweek CD-ROM, it took a long time to display the magazine's logo and play the introductory sound bit.

Worked examples

Example 1 — a first encounter with Sony Multimedia CD-ROM Player

Start with the simplest possible case. Write down what Sony Multimedia CD-ROM Player 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 Sony Multimedia CD-ROM Player 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 Sony Multimedia CD-ROM Player 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 Sony Multimedia CD-ROM Player

In research
Sony Multimedia CD-ROM Player 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 Sony Multimedia CD-ROM Player 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
Sony Multimedia CD-ROM Player is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audiovisual introductions in 1992, Compact disc, Computer-related introductions in 1992, so understanding it makes those chapters shorter.
In everyday life
Look for Sony Multimedia CD-ROM Player 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.
