ABSTRACT:
A device to turn on a disk formatter's write gate and NRZ line drivers with minimal delay from a sector pulse. The device utilizes a look-ahead scheme to asynchronously qualify a sector pulse to drive the write gate and enable the NRZ output drivers. The write gate and NRZ line drivers are conditionally enabled by a sector pulse and are held in the enabled state until the disk formatter provides an enable signal. The enabled NRZ line drivers provide binary zeros until actual data is provided to the drivers.
