近年来,盒式磁带录音机已进入到我国城乡居民家庭中。录音/放音质量的优劣,虽然与录音机质量有关,但如何正确选用磁带也是极其重要的。盒式录音机所用的磁带可分为普通磁带(氧化铁带)、铬带(二氧化铬)和金属磁带等。使用时,应根据它们的性能、特点来选择。 1.氧化铁(Fe_2O_3)磁带 这种磁带又分为低噪音(LN)带、低噪音高输出(LH)带和高性能LH带。 LN带的电磁性能稳定,中低音频响较好,但高音较差,宜作8kHz以下的音域录音,一般作语音带。这类磁带有日立公司和卡西欧公司的LN型磁带。 LH带的性能较LN带优越,噪音较低、高频特性较好、输出电平高,可用于一般的音乐录音。TDK公司的D型、SONY公司的CHF型磁带均为LH带。 高性能LH带是一种优质的高性能常规磁带,它具有良
In recent years, cassette tape recorders have entered our country’s urban and rural households. Recording / playback quality pros and cons, although the quality of the recorder, but how to correctly select the tape is extremely important. Cassette tape used in the tape can be divided into ordinary (iron oxide), chrome (chromium dioxide) and metal tape. Use, should be based on their performance, characteristics to choose from. 1. Fe2O3 (Fe2O3) tape This tape is divided into low noise (LN) band, low noise high output (LH) band and high performance LH band. LN with electromagnetic stability, bass sound better, but the treble is poor, should be made for the following 8kHz range recording, the general voice band. These tapes have LN tapes from Hitachi and Casio. LH band performance superior to the LN, lower noise, better high-frequency characteristics, high output level, can be used for general music recording. TDK’s D-type, SONY’s CHF-type tape are LH band. High-performance LH belt is a high-quality conventional tape, it has good
