发明名称 Precedent and subsequent minor transitions to alleviate pulse crowding
摘要 In a magnetic recording system having a medium for storing information in the form of encoded digital data, an improvement in the recording head control circuit including means and a method for determining the temporal occurrence of a major write transition of the encoded digital data and producing a minor write pre-transition and a minor write post-transition each having a lower amplitude and an opposite direction to that of the major write transition thereby providing a readout pulse corresponding to the combined write transitions having a narrower pulse width and improved symmetry which enhances the accuracy in reading out the recorded digital data and increases the packing density in the storage medium of the recording system.
