ABSTRACT:
Method of optimizing a write current for at least one rotatable magnetic head and arrangement for carrying out such a method.
In a method of optimizing a write current for at least one rotatable magnetic head (K1, K2), in which method a write current (I) is applied to the magnetic head (K1, K2) as a test signal with a given number of graded amplitude values within a given time interval and this test signal is recorded on the magnetic tape (5) by the magnetic head (K1, K2), the total given number of graded amplitude values of the write current (I), which is applied to the magnetic head (K1, K2) as a test signal, is applied to the magnetic head (K1, K2) within a single scanning period (T) of this magnetic head.
