Abstract
Write and read bias current control circuits are programmable through a control port. Both the read head bias DAC and the write DAC are controlled through a control port and both DACs use current as an input reference. The write and the read bias currents have constant reference current components which are set externally. The write and the read bias currents additionally have components which are a product of the reference current and a digital word loaded into an associated one of the DACs.
