摘要： A read-after-write head (100) for four channel azimuth recording in one mode of operation and two channel non-azimuth recording in another mode of operation. Four forward write head gaps (104, 106, 108, 110), four read head gaps (120, 122, 124, 126), and four backward write head gaps (112, 114, 116, 118) are geometrically positioned within a rotatable and laterally indexable face plate (102) of a recording head housing. The read and write head gaps collectively provide four forward write channels, four read channels, and four backward write channels. During the azimuth mode of operation, the head is rotated to the preselected positive or negative azimuth angle and all of the read and write channels are utilized. During the non-azimuth, or vertical, mode of operation, write channels two and four are used in combination with read channels one and three to provide two channel non-azimuth, or vertical, operation.
摘要翻译：在一种操作模式下的四通道方位记录读写头读取头（100）和在另一操作模式下的两通道非方位记录。四个向前写入头部间隙（104,106,108,110），四个读取头间隙（120,122,124,126）和四个向后写入头部间隙（112,114,116,118）几何地位于可旋转和记录头壳体的侧向可转位的面板（102）。读写头间隙共同提供四个正向写入通道，四个读取通道和四个反向写入通道。在方位操作模式下，头部旋转到预选的正或负方位角，并利用所有的读和写通道。在非方位或垂直操作模式期间，将两个和四个写入通道与读取通道一和三组合使用以提供两个通道非方位或垂直操作。
