description Information transfer apparatus in which a transducer 150F is movable by a solenod 130F from an inoperative position separated from a moving information carrying magnetic disk 20F towards the disk into engagement therewith in response to a transducer load command signal on line 208 which is applied to a control system connected to the solenoid to energise it. The control system is such as to produce an initial fast rising current in the solenoid to move the head quickly into close proximity with the disk, a slowly rising subsequent current in the solenoid to engage the head with the disk gradually, and a final fast rising current in the solenoid for completing the engagement pressure of the head on the disk.
