In this study, several read/write tests were conducted using a novel ferroelectric data storage test system equipped with a spindle motor, targeted at high-speed data transfer using a single probe head. A periodically inverted signal can be read out correctly with a bit rate of 100 kbps using this test system, and 10 Mbps data transfer is also possible during writing operations. The effect of a dc-offset voltage applied to the writing waveform with high-speed probe scanning is discussed. In addition, a novel noncontact probe height control technique was adopted to solve the problem of tip abrasion.
在本研究中,使用配备有主轴电机的新型铁电数据存储测试系统进行了多次读/写测试,目标是使用单个探头进行高速数据传输。使用该测试系统可以以100 kbps的比特率正确读出周期性反转信号,并且在写入操作期间也可以实现10 Mbps的数据传输。讨论了在高速探头扫描时施加到写入波形上的直流偏置电压的影响。此外,采用了一种新颖的非接触式探头高度控制技术来解决探头磨损问题。
