All About Ultimate High Quality CD (UHQCD)
Many years have passed since the birth of the Audio Compact Disc (CD) back in1982. By use of High-Quality materials and a totally different manufacturingmethod, the definitive version of audiophile audio CD was born. Playable on anyCD player, the Ultimate High Quality CD greatly surpasses all previous CDsbefore it!
The Ultimate High Quality CD (UHQCD):
UHQCD is a radical change to the CD manufacturing process itself. Theconventional wisdom about CD manufacturing, which had remained largely unchangedacross the world for over 30 years, has been exhaustively questioned. Throughthis effort, the ultimate in quality was attained – a level of quality that iscertainly impossible to achieve with existing CD discs.
The Ultimate High Quality CD was developed through an effort to improve audioquality by simply upgrading the materials used in ordinary CDs to higher qualitymaterials. For the substrate a high-transparency and high-fluidity polycarbonate(a type of plastic) of the type used for LCD panels was used, while for thereflective layer, low-cost, common aluminum was replaced with a unique andexpensive alloy of high-reflectivity.
Differences in manufacturing methods:
Conventional CDs are produced using the technique of injection molding to form”pits” of data on polycarbonate material. Metal plate on which “pits”representing audio source data are formed is used as a die. This is called the “stamper.”Polycarbonate is melted at high temperature and poured into the die to duplicatethe pit patterns on the stamper.
This method is efficient because it enables high-speed production, but it doesnot enable totally accurate or complete duplication of the pits on the stamper.As a melted plastic, polycarbonate is inevitably viscous, so it cannot penetratecompletely into every land and groove of the tiny pits of the stamper.
The Ultimate High Quality CD photopolymer is used instead of polycarbonate toreplicate the pits of the stamper. In their normal state, photopolymers areliquids, but one of their characteristic properties is that they harden whenexposed to light of certain wavelengths. The advantage of this property, perfectreplication of very finely detailed pits was achieved. Photopolymers in theliquid state are able to penetrate into the tiniest corners of pits on thestamper so that the pattern of the pits is reproduced to an extremely high levelof accuracy. The Ultimate High Quality CD reproduces audio with greaterprecision and at a level that is impossible to achieve using conventional CDproduction technology!
