Abstract
Tape recorder having a group of write heads which are arranged like a matrix in rows and columns, with each write head assigned in one row line and in one column line, and having a driver circuit for passing current through the row and column lines. A write head magnetizes a magnetic tape permanently only when its associated row and column lines have currents applied to them causing magnetic fields that reinforce one another in the magnetic tape. A common row return line is provided to which all the row lines are connected and a common column return line is provided to which all the column lines are connected.
