日本索尼公司最近已研制成两种大容量读写放大器集成电路。这些集成电路可用于硬质磁盘传动装置或简易盒式磁盘传动装置。一种读写放大器集成电路的型号为CXA1660Q,它采用的是使磁头微调电路超细化的脉冲,能用于硬质磁盘传动装置,它可以大大减小误差率,而且可增加 Japan’s Sony has recently developed two kinds of high-capacity read-write amplifier integrated circuits. These integrated circuits can be used for hard disk drives or simple disk drives. A read-write amplifier integrated circuit model CXA1660Q, which uses the fine-tuning the head fine-tuning the pulse can be used for hard disk drives, which can greatly reduce the error rate, but also increase
