Patent ID: 10977232

Abstract:
A magnetic tape cartridge secured with a blockchain is disclosed. The magnetic tape cartridge includes a solid-state cartridge memory, a reel of magnetic tape containing data, and a blockchain having a series of blocks. Each block in the blockchain contains a hash digest based on a portion of the data stored on the reel of magnetic tape and data pointers that link that portion of data stored on the reel of magnetic tape to each respective block. The blockchain blocks are stored in the solid-state cartridge memory. The portion of data upon which the hash digest is based is not redundantly stored in the solid-state cartridge memory with the block. The portion of data may be a logical volume, a logical partition, or all data stored on the reel of magnetic tape. The magnetic tape cartridge may also include a table containing pages stored within the solid-state cartridge memory with one of the pages being allocated for containing the blockchain.
