摘要
混合记录以激光辅助热磁记录和磁通检测读出为主要特征,具有记录密度潜力大、读出灵敏度高和分辨率高等一系列优点,是一种很有潜力的记录方式。论文设计了一个混合记录热效应模拟实验系统,该系统由单片机定时控制激光器加热样品,用热电偶作传感器,经放大后通过数据采集卡输入计算机,经数字滤波得到模拟样品温度与加热时间的关系。
Hybrid recording is characterized by laser-assisted recording and flux detection readout with advantages of super high-density,high resolution and high sensitivity.It is a promising recording method.This paper designs a system of hybrid recording heat domino simulation.This system uses microcontroller to control the laser,which is used to heat the sample.It regards a thermocouple as the sensor.After crossing amplifier,it is input into the computer through a data acquisition card.Then it gets the relations between the temperature of the simulating sample and heating time after digital filter.
