Abstract

Array recording heads used in high speed magnetic printing require a stationary recording head with the number of recording elements equal to the product of the word and bit line drivers. Magnetic printing systems using post head elements as the pel (picture element) recording device have been described in the literature [1,2]. The bitlines are generally the high duty cycle lines in the array multiplexing operation, for example, a magnetic recording head with 4096 elements will require a minimum of 64-word and 64-bit drivers to multiplex address any head element in the array. To address all the heads in the array, for one writing cycle, each word driver is addressed once while the bit drivers are addressed 64 times (equal to the number of word drivers).
