Abstract

This slidable retraction tool 10 is used for retracting magnetic transducer assemblies 11 from a normally loaded position against a disk 13, to a retracted position away from the disk surface. When the transducers are retracted, the arm 12 which carries the transducer assemblies can be initially positioned between respective magnetic disks 13 in a disk pack arrangement.

Retraction Device for Magnetic Transducer Assembly

This slidable retraction tool 10 is used for retracting magnetic transducer assemblies 11 from a normally loaded position against a disk 13, to a retracted position away from the disk surface. When the transducers are retracted, the arm 12 which carries the transducer assemblies can be initially positioned between respective magnetic disks 13 in a disk pack arrangement.

The tool includes a wedge-shaped end 14 defining several cam portions 15 and is shown inserted through a passageway in the arm 12.

As the tool end is moved to the left, the cams 15 contact respective plane-shaped retraction lever portions 18 of the suspension systems 19 that couples the magnetic transducer to the arm. Continued movement forces levers 18 against blocks 21 which are attached to arm 12, thus causing suspensions 19 to pivot, whereby the transducers are lifted from the disks. The cam is shown as part of the arm assembly although it may be removable from the arm. In addition, one tool can be used to retract transducers on both sides of the arm, and also to retract a multiplicity of aligned transducers positioned against a single magnetic disk surface.
