33/45转黑胶唱片
名称:33/45转黑胶唱片
产地:德国
年份:20世纪50年代
器材简介:
全新的唱片于1948年在哥伦比亚唱片公司问世了,其发明人是该公司的首席工程师皮特·格德马克(PeterGoldmark).他本人是个古典音乐爱好者。格德马克领导的研究小组经过多年的研究,从唱针唱臂,再到唱盘材料等许多地方对唱片进行了根本性的改革。他们采用钻石做唱针,乙烯基塑料(Vinyl)为唱片材料,把唱片转速降到每分钟33.3转,并增加沟纹密度,使得一张12英寸(约30厘米)唱片每面可放二十多分钟的音乐。这就是人们常说的密纹唱片,又叫“长时唱片”(LongPlay,LP)。
RCA公司认为单曲唱片还将延续很长的时间,因此他们推出了一种新的规格:45转唱片。它直径小,唱片薄,又不容易碎,运输成本低,十分适合讲究时效的单曲市场。另外,45转唱片材料上,由于氯醋共聚树脂代替了紫胶树脂,唱片的颗粒变细,微小的振动也能录制下来,这样高保真的效果得到进一步体现。

It is small in diameter, record is thin, and not easy to be broken, transportation cost is low, very suitable to single market. In addition, materials of 45 RPM record was vinyl chloride, particles on record was thinner, tiny vibration can also be recorded, so high fidelity effect can be further reflected.
