  • 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.

  • 1. Explain CD (COMPACT DISC) TECHNOLOGY
    1. Explain CD (COMPACT DISC) TECHNOLOGY A compact disc, also known as a CD, is a plastic optical disc with a metalized surface that is used for digital data storage.. This format was later adapted for storage of data (CD-ROM), write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Discs (VCD), Super Video Compact Discs (SVCD), Photo CD, Picture CD, CD-i, and Enhanced CD. When a compact disc is played, the information is read by a laser and converted into sound that represents an original audio source. The CD's storage capabilities have expanded alongside its technology to read other data like CD-ROM for computers or DVD and Blu-ray for video. A standard CD typically holds 74 to 79 minutes of audio. The CD debuted in 1982 under Philips Electronics and Sony Corporation. The basic compact disc is simple in appearance, but consists of multiple layers. The base layer is polycarbonate plastic which holds the digital data. This layer is topped by an aluminium coating that serves to reflect the laser that reads the disc's information. (In rare instances, silver or gold may be used in place of aluminium). A clear layer of shiny acrylic protects the aluminium. The standard CD has a 12 cm diameter and a 1.2 mm thickness. From its centre outward, it consists of a spindle, a clamping ring, a stack ring, a mirror band, an information area and the rim. The CD's data layer is comprised of billions of tiny indentations called pits that are invisible to the human eye.

  • Signal Processingof the Compact-Cassettedigital Recorder
    PAPERS Signal Processingof the Compact-CassetteDigital Recorder N. SAKAMOTO, T. KOGURE, M. SHIMBO, AND H. KOMAE Acoustic Research Laboratory, Matsushita Electric Industrial Co., Ltd., Kadoma, Osaka, Japan The signal-processing techniques for compact-cassette digital recording are of interest to those concerned with consumer audio equipment. A cassette digital tape recorder using a metal-evaporated tape has been developed together with a high-density ferrite head having 12 tracks of 120-p,m track width and 0.3-p.m gap length per channel. Specially designed digital signal-processing circuits include circuits for signal generation, modulation, error correction, and signal control. The digital modulation scheme called FEM-4 is a new and key item of the design. The practical design and system concepts are outlined. 0 INTRODUCTION and track density for various systems and shows clearly that these quantities should be higher for a DAT than When the Compact Disc system was introduced to for the conventional analog system. These are the causes the Japanese market, audio enthusiasts showed keen interest in the system, and Compact Disc players began for most of the difficulties. Moreover, the relationship disappearing from the market because of hardware between these factors is complex. For instance, the required linear density depends on the digital modulation shortages. Demand has now developed for a consumer scheme, track density, sampling rate, quantization, tape digital audio tape recorder (DAT), a system that permits speed, and so on. Suitable recording density depends digital recording as well as playback. DAT system developments were announced by several also on an adequate playing time and on the reliability companies, followed by demonstrations at audio shows, desired in a tape recorder for consumer use.
