1. A thin film magnetic data transfer transducer, comprising:
- a substrate having a surface;
a first predetermined pattern of thin film material formed from electrically conductive material, said first predetermined pattern of thin film material having a portion thereof disposed on said surface of said substrate;
a first substantially magnetically permeable piece of material formed on at least a portion of said first predetermined pattern of thin film material disposed on said surface of said substrate;
a second predetermined pattern of thin film material formed from electrically conductive material, said second predetermined pattern of thin film material being formed on a portion of said first substantially magnetically permeable piece of material and in electrical communication with said first predetermined pattern of thin film material whereby said first and second predetermined patterns of thin film material form a coil about said first substantially magnetically permeable piece of material;
a substantially magnetically non-permeable piece of material formed on and outwardly extending from at least a portion of said first substantially magnetically permeable piece of material and said second predetermined pattern of thin film material; and
a second substantially magnetically permeable piece of material formed on at least a portion of said substantially magnetically non-permeable piece of material and in communication with said first substantially magnetically permeable piece of material whereby said second substantially magnetically permeable piece of material and said substantially magnetically non-permeable piece of material are formed as a head gap outwardly extending from and as a part of said thin film magnetic data transfer transducer.

Abstract
A disk storage device has a simultaneous data transfer head means (2284) having a plurality of data transducer means (2570) for the simultaneous storage and/or retrieval of a plurality of data on a disk means. The device makes it feasible for the simultaneous transfer of data to and from a disk storage device with a storage area formed thereon (2272), thereby increasing the I/O between the processing unit and the storage device. The magnetic data transfer transducer is fabricated on a substrate by thin film techniques with each element, including the head gap, being successively formed on more elements previously formed.
