| 术语 | magnetoresistive head |
| 释义 | magnetoresistive head 磁阻磁头 Magnetic bead made from magnetoresistive element (element with its magnetic resistance varying with applied magnetic field strength). It is mainly used as read out head in high track density magnetic digital recording unit. Its advantages are: the amplitude of read out signal is independent of the relative velocity between the head and the medium, and sensitivity is much higher than that of the inductive type head. 由磁阻元件(即磁阻随外加磁场强度变化而变 化的元件)构成的磁头。它主要用作高磁道密度的数字磁记录读出磁头。其特点是读出信 号的幅度和记录媒体与磁头的相对运动速度无关,且读出灵敏度比感应式磁头高得多。 |
