AI Technical Summary

Technical Problem

Existing cassette storage devices face the challenges of increasing size and cost when storage capacity increases, especially when storing ancillary information related to the cassette, where traditional methods are difficult to effectively manage and expand storage capacity.

Method used

It adopts a contactless communication medium, and performs contactless communication between the processor and memory and the external communication device. It utilizes multiple storage fields contained in the storage block, including specification-dependent and non-dependent storage fields. The processor writes the accompanying information related to the tape cartridge according to the instructions, locks the storage area and generates a read-only area, so as to achieve efficient storage and management of information.

Benefits of technology

It enables the efficient storage and management of large amounts of ancillary information related to magnetic tape cassettes without increasing the size and cost of the cassette storage, thereby improving storage capacity utilization and information management efficiency.

Abstract

A non-contact communication medium has a processor and a memory built-in or connected to the processor, and performs non-contact communication with an external communication device. The memory has a storage block storing information about attributes of the non-contact communication medium, and the storage block includes a plurality of storage fields. The plurality of storage fields includes a specification-independent storage field storing information independent of a specification of a magnetic tape cartridge on which the non-contact communication medium is mounted. The processor writes accompanying information about the magnetic tape cartridge into the specification-independent storage field in accordance with an instruction given to the non-contact communication medium from the external communication device by performing the non-contact communication.
