Novel intelligent tape unit and data processing method

Abstract

The invention discloses a novel intelligent tape driver and a data processing method thereof, belonging to a chip-tape storage device and a data processing method thereof, which comprises a memory chip arranged inside a tape cassette and an interface circuit thereof, and a memory chip read-write module arranged on the tape driver and an interface circuit thereof, wherein, the two interface circuits are electrically connected by a pair of metal contacts. The tape driver processor is connected with the memory chip through an interface circuit after being connected with the memory chip read-write module. Only a data area is arranged on the tape. The memory chip is divided into an index mark section, a writing cache, a read cache and other data section, wherein, both reading and writing requests of data are performed in the reading and writing caches, other than in the tape driver. The combination of the sequential memory of the tape and the random memory of the chip reduces the frequent mechanical motion of the tape driver, thereby improving the retrieval speed and the memory efficiency and prolonging the service life of the tape driver.

Description

technical field [0001] The invention relates to a computer data storage device, specifically a magnetic tape drive which combines the sequential storage mode of magnetic tape with the random storage mode of semiconductor memory chips. Background technique [0002] Data streaming tape drive is the most widely used tape drive, it is an important means of data backup. However, due to the sequential storage method, it takes a long time to locate and retrieve the magnetic tape, resulting in a low overall speed of the magnetic tape system and very inconvenient retrieval. As the storage density of magnetic media continues to increase, the capacity of magnetic tapes also increases, making this problem even more prominent. [0003] The speed of a tape drive is primarily affected by the motion of the tape. During the positioning and retrieval process of the magnetic tape, the magnetic tape must move continuously, and read and write can only be started after the designated position i...

Problems solved by technology

However, SONY's MIC chip capacity is very small, and the storage capacity (64kbit / 16kbit) is very limited. When searching, it is still necessary to search on the tape, which only improves the access speed of the tape to a certain extent.
