Magnetic head with read and write coils and a circuit for interrupting a mutual induction of the coils
摘要：
An apparatus provided with a magnetic head including a core, a writing coil and a reading coil wound around the core; a writing circuit connected with the writing coil for driving the writing coil; a reading circuit connected with the reading coil for generating a read signal based on an output of the reading coil; a power source for supplying an electric power to the writing circuit; and a controller for suspending the supply of electric power to the writing circuit when the reading circuit is in operation.
