Abstract

This manually operated magnetic tape data recorder does not have a power supply. The recorder is suited for use as a credit sale recorder at a gasoline service station or as a portable public utility meter reader. It produces a magnetic tape record that can be entered directly into an electronic data processing system for billing or other accounting purposes. Basically, the apparatus exploits the principle of magnetic copying, except that the master record, instead of being an erasable, magnetized record, consists of a pattern of slugs, or inserts, of magnetic material. These inserts, in the case of a credit card or utility meter, are embedded in a fixed coded pattern in a plastic, or other non-magnetic carrier, to identify the account or meter number.

Magnetic Tape Transaction Recorder

This manually operated magnetic tape data recorder does not have a power supply. The recorder is suited for use as a credit sale recorder at a gasoline service station or as a portable public utility meter reader. It produces a magnetic tape record that can be entered directly into an electronic data processing system for billing or other accounting purposes. Basically, the apparatus exploits the principle of magnetic copying, except that the master record, instead of being an erasable, magnetized record, consists of a pattern of slugs, or inserts, of magnetic material. These inserts, in the case of a credit card or utility meter, are embedded in a fixed coded pattern in a plastic, or other non- magnetic carrier, to identify the account or meter number. To record variable data such as the amount of sale or consumption, the inserts are embedded in movable slides or wheels which are manually aligned to produce a coded pattern of inserts corresponding to the variable data.

When the requisite pattern of inserts is established by manipulation of the credit card and slides, a magnetic tape is pressed against the inserts and a permanent magnet passed over the tape. The pattern of the inserts is thus transferred to the tape as discrete magnetized spots in the tape. In the absence of a magnetic slug in the air gap of the permanent recording magnet, the strength of the flux field sure rounding the air gap is insufficient to overcome the c...
