    • The drawing diagrammatically illustrates the lay-out of a head array. The array comprises 64 sub-arrays, only sub-arrays B1 and B64 being shown. The sub-array 81 comprises 64 heads, each had being represented by two pole pieces, shows as square dots. 64 word lines (not shown) linkthe pole pieces, the first word line linking cores 63, 64; the second 61, 62; and the last cores 1, 2. A single bit line links the 64 cores in sub-array B1. The bit line is linked with odd numbered cores in one sense and with even numbered cores in the opposite sense. A pole piece is uniquely selected by energising the appropriate word line and then pulsing the bit line with a positive or negative pulse to select one or other of the two cores conditioned by the word line. The heads in each column are staggered in the x-direction so that when a recording is made by relative movement in the y-direction, the magnetic spot recorded by a head e.g. head 57 is contiguous with the magnetic spot recorded by the next consecutive head in the column. Further the magnetic spot recorded by the first head in each subsequent sub-array is contiguous with the magnetic spot recorded by the last head of the preceding sub-array.
    • 该图示意性地图示了头部阵列的布局。 该阵列包括64个子阵列,只显示了子阵列B1和B64。 子阵列81包括64个磁头,每个磁头由两个极片代表,表示为方形点。 64条字线(未示出)连接极片,第一字线连接芯63,64; 第二个61,62; 和最后的核1,2。单个位线连接子阵列B1中的64个核。 位线在一种意义上与奇数编号的核心相连,偶数编号的核心在相反意义上相连。 通过激励适当的字线,然后用正脉冲或负脉冲脉动位线来选择磁极片,以选择由字线调节的两个核心中的一个或另一个。 每列中的头在x方向上交错排列,从而当通过在y方向上的相对运动进行记录时,由头记录的磁点例如, 头部57与由列中的下一个连续头部记录的磁性点邻接。 此外,由每个后续子阵列中的第一个磁头记录的磁点与由前一个子阵列的最后一个磁头记录的磁点邻接。
