Abstract

Data magnetically recorded on a tape strip is normally processed directly on the strip which leads to strip wear and head registration problems. Elimination of these is accomplished by transferring the data from the tape strip to some other magnetic medium for processing.

Random Access Strip File

Data magnetically recorded on a tape strip is normally processed directly on the strip which leads to strip wear and head registration problems. Elimination of these is accomplished by transferring the data from the tape strip to some other magnetic medium for processing.

A pluggable tape strip file is plugged into a tape processing unit and adjusted to a selected strip. Upon energization of the strip eject solenoid, a flexible return guide rises through a slot in the bottom of the file support to push the selected strip from the pluggable strip file into the strip feed rollers. The strip then passes between the strip to drum transducer and the nickel-cobalt processing drum. During this time it is subjected to a magnetic field by the transducer. This enhances the magnetic pattern on the strip to reproduce the tape strip data on the processing drum.

The strip is then erased and stored in the strip storage guide while the reproduced data is read from the processing drum, updated or other wise acted upon, and re-recorded on the drum. Energization of the strip return solenoid causes the tape strip to be again brought into rolling contact with the processing drum. During such time a magnetic field is provided by the drum to strip transducer to effect transfer of the information from the processing drum to the strip.

Rotation of the processing drum causes the strip to be propelled down the strip return path between the return drive rollers and...
