现今,城市里几乎每家都有录音机。国产录音机都用磁带录音,而日木已研制出可录音的激光盘。本文即介绍两家日本公司用不同技术制作的可录音激光盘。最近,日本先锋和日立公司都宣布,他们在制作可录音的家用激光盘方而获得技术上的突破。两家公司都可以逐渐为消费者提供激光盘音机和一次性写入的空白盘。虽然,两种方案都仿效流行的激光盘模拟调频视频信号录音类型,然而,他们的制作技术却根本不同。 Almost every city in town today has a recorder. Domestic tape recorders are tape recording, and Japan has developed a recordable laser disc. This article describes two Japanese companies can use different technologies to produce recordable laser disc. Recently, Pioneer Japan and Hitachi announced that they have made technological breakthroughs in the production of recordable home laser discs. Both companies are able to gradually provide consumers with a laser disc and a write-once blank disc. Although both programs follow the popular laser disc analogue FM video recording types, their production techniques are fundamentally different.
