  • Historical Development of Magnetic Recording and Tape Recorder 3 Masanori Kimizuka
    Historical Development of Magnetic Recording and Tape Recorder 3 Masanori Kimizuka ■ Abstract The history of sound recording started with the "Phonograph," the machine invented by Thomas Edison in the USA in 1877. Following that invention, Oberlin Smith, an American engineer, announced his idea for magnetic recording in 1888. Ten years later, Valdemar Poulsen, a Danish telephone engineer, invented the world's frst magnetic recorder, called the "Telegraphone," in 1898. The Telegraphone used thin metal wire as the recording material. Though wire recorders like the Telegraphone did not become popular, research on magnetic recording continued all over the world, and a new type of recorder that used tape coated with magnetic powder instead of metal wire as the recording material was invented in the 1920's. The real archetype of the modern tape recorder, the "Magnetophone," which was developed in Germany in the mid-1930's, was based on this recorder.After World War II, the USA conducted extensive research on the technology of the requisitioned Magnetophone and subsequently developed a modern professional tape recorder. Since the functionality of this tape recorder was superior to that of the conventional disc recorder, several broadcast stations immediately introduced new machines to their radio broadcasting operations. The tape recorder was soon introduced to the consumer market also, which led to a very rapid increase in the number of machines produced. In Japan, Tokyo Tsushin Kogyo, which eventually changed its name to Sony, started investigating magnetic recording technology after the end of the war and soon developed their original magnetic tape and recorder. In 1950 they released the frst Japanese tape recorder.

  • The Evolution of DVD ECE 571G March 10, 1998
    The Evolution of DVD ECE 571G March 10, 1998 Raed Sunna Dave Tompkins This report is dedicated to some of the (relatively) unsuccessful or short-lived video and audio formats from the past 40 years: 3D Television 8 -Track ADAT Audiopak Betamax CD Plus CD Video CD-I Cinerama DAT DCC Echomatic EVR Fidelipac MiniDisc Photo CD Playtape Port-a-Pak ScoopMan S-DAT Selectavision Smell-O-Vision U-Matic Videodisc Introduction The DVD (Digital Versatile Disc) is on the verge of defining history in both the computer industry and the home entertainment industry. Millions of dollars have been invested into DVD, with a lot of investors hoping it becomes the next home appliance. In order to consider where DVD will end up it will help to examine a few key questions: · What does the scene look like before DVD? · How does DVD fit into the existing scene? · How does the technology of DVD compare? · What will happen with DVD? This report tries to answer those questions, by tracing the history from the turn of 20th century to the turn of the 21st and beyond. Taking a qualitative approach to how DVD will be accepted, this report will help answer some of the questions that numbers just can’t answer. It should be noted that many of the views, dates and statistics in this report are based on very North American (or more simply, American) perspectives. This was done for several reasons, but primarily because numbers and information about American culture is commonly available. However, it should be noted that this Ameri-centric view is an outdated concept, and that the world and global economies are more important now than ever before.

  • Welcome to the World of Media Preservation!
    Welcome to the World of Media Preservation! Joshua Harris Media Preservation Coordinator UIUC Libraries “Some believe that the challenge of preserving sound recording collections is narrow and easily framed— simply a matter of copying old recordings to a new medium. The preservation process, however, entails much more than transferring a recording and saving it as a digital file; indeed, these two steps fall somewhere in the middle of a lengthy chain of events.” The preservation of recorded sound collections entails a set of processes requiring careful planning and a sophisticated technical infrastructure. It comprises several steps and requires important decisions that will affect what recordings are saved and what compromises may have to be made to ensure that the greatest number of recordings will be saved.” -The State of Recorded Sound Preservation in the United States. Council on Library and Information Resources and The Library of Congress. August 2010. So what really is “A/V (Media) Preservation???” • Conservation: Safeguarding and protection of original materials from damage. Involves hands-on intervention and repair of physical materials. • Preservation: All actions taken to maintain an object in its existing condition, minimize the rate of change, and slow down further deterioration. Includes duplication, copying, or migration of objects with limited life expectancy • Restoration: Actions taken to modify the existing material and structure of an object in order to return it to a known earlier condition, e.g. as new, or original. So what really is “A/V (Media) Preservation???” • "Preservation is the totality of the steps necessary to ensure the permanent accessibility – forever - of an audiovisual document with the maximum integrity“ -CCAAA • In reality, A/V Preservation includes preservation, conservation and restoration.

  • Sound Design and Recorded Music Part One
    PART ONE: SOUND DESIGN AND RECORDED MUSIC Far too often in today’s production work the individual assigned to be the designer of sound and other accompanying music simply goes to a collection of prerecorded music (or “101 Sound Effects”) and transfers the required piece to whatever medium of playback is being used for production. Anyone trained on the equipment can do this and the expenditure of creative thought and planning is practically nil. If a sound designer is participating on a production team, the evolution of the production will be influenced by each designer’s input and indeed, the final effect may not be found on a prerecorded compact disc (CD). And why should it be? The costume designer cannot shop for flapper dresses of the 1920s nor can the scenic elements be procured at any hardware store. Part of the pleasure, indeed responsibility, of each designer is to create the solution that captures the look and feel required by the specific production. And part of that feel is certainly enhanced by the choices of the sound designer. Because theatrical production is a total design effort, it is incumbent on each designer to understand the script, and be in accord with the other designers, the director, the producer, and the writers. This should include not only theatre but film, television and any other installation which is designed to affect an audience in a particular planned and organized manner. This is not always the case. The best assurance of good teamwork is understanding and acceptance between designers about the paths the production will take.

  • Cassettes Ever Sold in the United States
    WELCOME WELCOME At National Audio Company we strive to provide all your analog and digital audio media needs. We are your one-stop source for professional cassette tapes, digital media, duplication, and packaging. Steve Stepp - Steve Stepp President, NAC This catalog supersedes all previous prices, fliers, and brochures. Prices are correct at the time of printing. We reserve the right to raise prices at any time. NATIONAL AUDIO COMPANY CELEBRATING 50 YEARS National Audio opened its doors in 1969, off ering some of the first audio cassettes ever sold in the United States. Professional grade Ampex recording tapes and Fidelipac broadcast cartridges were initially off ered. Manufacturing operations began in 1980 at the Springfield, Missouri plant with the introduction of the Audio Pro cassette brand. The new product line soon became the recognized industry standard in duplication, as production expanded to a 28,000 square foot facility to keep pace with demand. By the 2000’s, digital audio had come of age. Owner Steve Stepp did not follow competitors withdrawing from the audiocassette market. Instead, he pledged to manufacture the last audiocassette ever produced and envisioned a new horizon for the medium. National Audio’s 135,000 square foot manufacturing plant, for audio tape, duplicating, and packaging, is still located in Springfield, Missouri. Now in our 50th Anniversary Year, National Audio customers include major motion picture studios and 3500 record labels. Local and regional bands, government agencies, books on tape, instruction providers, religious organizations, and the scientific community are also among our family of customers. In-house audio engineers can clean up imperfections in sound.
