The soft magnetic spinel ferrites, by far the most important cubic ferrites, were first introduced by Philips under the trade name Ferroxcube (14) and are now widely commercially available under various trade names. The world market for soft magnetic ferrites amounts to about one biUion dollars (1991), about 350 million dollars of which is in the United States.

Ferroelectric—polymer composite devices have been developed for large-area transducers, active noise control, and medical imaging appHcations. North American Philips, Hewlett-Packard, and Toshiba make composite medical imaging probes for in-house use. Krautkramer Branson Co. produces the same purpose composite transducer for the open market. NTK Technical Ceramics and Mitsubishi Petrochemical market ferroelectric—polymer composite materials (108) for various device appHcations, such as a towed array hydrophone and robotic use. Whereas the composite market is growing with the invention of new devices, total unit volume and doUar amounts are small compared to the ferroelectric capacitor and ferroelectric—piezoelectric ceramic markets (see Medical imaging technology). 

Principal producers of ferroelectric capacitors are (110) Murata Manufacturing Co., Ltd., Kyoto, Japan Kyocera Corp., Kyoto, Japan Philips Electronics, N.V., Eindhoven, the Netherlands and NEC Corp., Tokyo, Japan. Principal piezoelectric ceramic component producers are (110) Murata Manufacturing Co., Ltd., Kyoto, Japan Motorola, Inc., Schaumburg, lU. EDO Corp., College Point, N.Y. Morgan Matroc, Inc., Bedford, Ohio Kyocera Corp., Kyoto, Japan and Philips Electronics, N.V., Eindhoven, the Netherlands. 

The physical CD format has been recognized as an industry standard all CD-ROMs are of the same size, and data are stored in the same way in the same physical format. Details are put down in the so-called Yellow Book (Philips/Sony). 

The CD-I (compact disk-interactive) is a low cost alternative to the CD-ROM for the entertainment industry. CD-I is a subset of the CD-ROM standard data format. It allows the digital storage of data, audio, and video information in a form that permits rapid interaction with a computer. CD-I is compatible to CD-ROM and to CD-AD 0 = 120 mm. The definition of the CD-I format is put down in the Green Book (Philips/Sony). 

CD-R (CD-recordable) is a writable, nonerasable disk, also called CD-WORM or CD-WO (CD-write once). Permanent marks are produced by a focused laser beam. The definition of the CD-R format and of the erasable—rewritable EOD /MO-R format is put down in the Orange Book (Philips/Sony). 

Glass substrates are used commercially for 5.25 in. EOD(MOR) disks only by a few manufacturers (eg. Philips, Hitachi) in contrast, for CD-ROM and WORM memories with disk diameters exceeding 5.25 in. (eg, 12 in. and 14 in.), glass substrates are employed frequently. 

Eor EOD disks with 86 mm (3.5 in.) diameter and for Sony s Mini-Disk (67 mm diameter), modified BPA-PC is used exclusively for EOD disks with 130 mm diameter, modified BPA-PC (mainly) as well as glass (eg. Philips, Hitachi) are used.
