Abstract

In binary to decimal converting device 31, binary coded address instructions are converted into sixteen decimal values. The latter are used for operating selected solenoids 14. These through valves 19, control the axial displacement of shaft 26 of hydraulic positioning device 27. The axial positioning of shaft 26 is effected by the rotational position of a four position drive.

Data Storage System

In binary to decimal converting device 31, binary coded address instructions are converted into sixteen decimal values. The latter are used for operating selected solenoids 14. These through valves 19, control the axial displacement of shaft 26 of hydraulic positioning device 27. The axial positioning of shaft 26 is effected by the rotational position of a four position drive.

Shaft 26 is connected to carriage 15. This controls the movement of drawer 10 sliding on rails 16 and of magnetic transducer 18. Drawer 10 contains sixty strip-shaped record carriers 11. Each has associated with it an index track 22 on magnetic disc 20. The data of track 22 is used for analyzing the information contained in a record carrier such as microfilm or punched tape.

The information of a selected record carrier 11 is analyzed. This is in such a manner that positioning device 27 moves drawer 10 into an analyzing position
17. Here the record carrier is engaged by a gripper and fed through a reading unit. At the same time, the associated index track is scanned.
