  • Binary output reader structure (BORS) with high utilization rate
    Patent number: 8208230
    Abstract: We disclose a magnetic read head, and method for making it, that operates in a binary rather than an analog mode. This greatly boosts signal amplitude for high area density recording as device dimensions get smaller. The device is well suited to the inclusion of side shields which further reduces side reading errors. The device has a utilization efficiency close to 100%.
