Abstract: An improved safety latch is provided for a data storage device, for locking the transducer carriage to restrain the data transducer to a predetermined landing zone during non-rotation of data storage disks and for releasing the carriage in response to airflow generated by disk rotation, the latch comprising an integral member including a moveable airvane disposed between two disks for being deflected by airflow generated by rotation of the disks, a latching member responsive to deflection of the airvane means to release the carriage and an integral counterweight. The latch includes a magnetic bias spring for providing a predetermined bias by magnetic field deflection to the latch in order to urge the latch into engagement with the carriage in the absense of airflow sufficient to deflect the airvane means to overcome the bias and thereby release the latch.
