An area at or near the front end of the tape 105 can be provided, which is known as "tape start" (BOT) as is known to those skilled in the art. In a single reel magazine, this is one or more entangled regions (leading blocks) near the front end of the tape that are loaded into the take-up spool 116 of the tape drive 115 as depicted in FIG. . In a dual reel magazine, the area of the tape near the center, about halfway between one reel and the other reel, is typically designated as a BOT, and it may include one or more windings. The double reel tape is also referred to as a midpoint loading belt. This BOT area is typically reserved for information about the tape, such as an index, and may include an indication of the location of the partitions 127A, 127B, 127C, etc. of Figure 5, as well as other information about the partition.

Referring to FIG. 4, an embodiment of the cartridge memories 104A, 104B, 104C, 104D, and 104E includes a communication interface 126 configured to communicate outside of the data storage port; and a memory system 130 configured To store information and communicate information to the communication interface.

The communication interface 126 can include a wireless interface or transponder that receives power and data from the interface 117 of the data storage drive and stores the data to the data storage drive when the data storage device 100 is installed in the data storage drive 115 Interface 117. For example, the wireless interface 126 is an RF wireless interface. An example is described in U.S. Patent No. 4,941,201. A high frequency inductive wireless interface can also be employed that has a sufficiently high frequency that the magnetic storage medium 105 is not adversely affected by the signal. Examples are described in U.S. Patent Nos. 4,650,981, 4,758,836, and 3,859,624. Alternatively, the sensing antenna for the wireless interface is shielded from the tape 105.

The antenna 135 receives the RF signal from the RF interface of the data storage drive, and the coupler 136 supplies the received signal to the power conversion circuit 140 and to the data demodulation transformer 142. The power conversion circuit 140 converts the received signal into a power current, and supplies the current on the line 144 to all devices in the data storage device that require power. The devices include the memory system 130, the data demodulator 142, and the data modulation. 145. The received signal from antenna 135 can be encoded, and data demodulator 142 receives the incoming encoded signal from coupler 136 and demodulates the signal to provide the data signal to memory system 130. The data signal from memory system 130 is provided to data modulator 145, which encodes the signal for transmission by coupler 136 and antenna 135 to the RF interface of the data storage drive.

The memory system 130 can include a memory processor 137, such as a logic or microprocessor chip, such as an Intel Pentium chip configured to operate in a low power environment such as a portable computer; and associated non- Volatile memory 131, which is also configured to operate in a low power environment.

The processor can have computer readable code embodied therein, the computer readable code containing appropriate security and encryption/decryption algorithms, and logic for accessing and operating memory 131. Memory 131 can include a non-volatile reservoir, as is known to those skilled in the art. The non-volatile memory can include a separate wafer 137 attached to a logic or microprocessor, or can include a portion of the same wafer. The computer readable code may be stored in the non-volatile internal memory of the processor 137 or may be stored in the non-volatile memory 131 and loaded into the processor 137. Alternatively, the memory 104 and the non-volatile memory 131 can be operated by a control system or processor of the data storage drive or by an associated host system.

Referring to Figure 6, an example of the contents of the cartridge memory 104 of the tape cartridge 100 of Figures 1, 2, 3 and 4 is illustrated. An example of the 匣-type memory 104 and its contents is described in the standard ECMA-319, June 2001, "Data Interchange on 12, 7 mm 384-Track Magnetic Tape Cartridges-Ultrium-1 Format", Appendix D-LTO匣Memory, pages 95 to 115. As an example, the 记忆-type memory 104 is arranged in regions of various sizes having information organized into "pages". The memory 104 can be similar to the memory and transponders used in "smart cards" as is known to those skilled in the art. An additional type of 记忆 memory can be foreseen by those skilled in the art.

The memory 131 of the memory system 130 can be formatted (as illustrated in FIG. 6) to include a header 150 and various information regions 151, 152. The header 150 will incorporate information about the information area and use of the information, and may incorporate specific identification and security information.

In accordance with an embodiment of the present invention, memory system 130 is formatted to allow association with at least one of a plurality of partitions 127A, 127B, 127C, etc. of a material storage medium. For example, the information area 151 of the memory system of the memory 104C can be associated with the partition 127C of FIG.

In this manner, each of the cartridge memories 104A, 104B, 104C, 104D, and 104E of the cartridge 100 of Figures 1, 2, 3, and 4 can be combined with a different partition 127A, 127B of the data storage medium of FIG. 127C and other related. This association may mean that the storage area contains information about the information of the associated partition. In addition, the association may include information contained in the storage area that allows the partition to be managed by the data storage drive or the host, the information including the security and processing of the data.

In addition, each logical partition may have its own physical owner, such as a data storage drive or a user of the host. Thus, a physical data storage medium or magazine may have multiple owners, each under the management of information incorporating independent cartridge memories 104A, 104B, 104C, 104D, and 104E.

In the case where multiple ports of memory serve multiple partitions, the access to the tape is virtualized and can be interfaced with a storage area network (SAN) interface to which the data storage device is attached.

In another embodiment, each of the cartridge memories 104A, 104B, 104C, 104D, and 104E is independently addressable.

In one embodiment, the communication interface of each of the cartridge memories includes a radio frequency interface that operates at a different frequency. For example, communication interface 126 of FIG. 4 includes circuitry 135 that includes an inductive antenna loop and capacitors, wherein the capacitors have different capacitances to provide different frequencies. Different frequencies will alternately allow simultaneous access to more than one or all of the ports in the memory by communication at all frequencies, or access to only one bank of memory at a particular frequency.

Alternatively, each of the communication interfaces 126 of the cartridge memory includes an addressable interface that is independently addressable. For example, each type of memory can have its own unique identifier. By inserting an identifier into an input/output (I/O) command (for writing to a 记忆-type memory and a self-following memory), reading to an individual 记忆 memory can be achieved. Write.

In another embodiment, each of the cartridges includes providing a separate password to obtain read and/or write access to the memory system. The password can be stored in the header 150 of the non-volatile memory 131 of FIG. The term "password" is used to refer to any suitable authentication algorithm to allow user access to information about the memory and/or associated partitions.

In another embodiment, the memory system of each of the cartridge memories is configured to format information to permit a subset of the plurality of partitions 127A, 127B, 127C, etc. of the data storage medium. Associated. For example, the information area 151 of the memory system of the memory 104C can be associated with the partitions 127B and 127C of FIG.

In yet another embodiment, at least one of the memory systems of the cartridge memory is configured to format information to permit redundancy between at least a portion of the information of the other of the cartridges. For example, the information area 151 of the memory system of the memory 104C can be associated with the partition 127B, and the information area 152 can repeat at least a portion of the header of the information area or the memory 104B. In addition, error post-failover information may be provided in header 150 or information area 151 such that failure of one of the 匣-type memories will cause erroneous back-shifting of redundant information in another 记忆-type memory And therefore does not cause a malfunction. Processor 137 may have the necessary algorithms to make the post-error transfer transparent to the user and/or provide an error flag or message to the user or manager.

Referring to FIG. 1, in accordance with an embodiment of the present invention, each of the cartridge memories 104A, 104B, 104C, 104D, and 104E is supported by a container 101 that is positioned such that the communication interface can, for example, be borrowed The interface 117 of the data storage drive 115 of FIG. 3 is simultaneously accessed outside the data storage port 100. Referring to Figure 4, in one embodiment, the jaw memory system is supported by the container such that the antennas 135 of each of the cassettes are oriented in a similar direction to allow simultaneous access. In an example, each of the cartridge memories is oriented at a substantially 45° angle with respect to the bottom and sides of the container 100 of FIG. 1 to allow for a data storage drive or an extractor via an automated data repository. Simultaneous access to all of the 记忆-type memories, which are relatively different angles.

Referring to Figures 3 and 7, in accordance with the present invention, control system 124 of, for example, data storage drive 115 provides for the allocation of the portion of the data storage medium 105 of data storage 100 to the storage memory 104A, 104B. The services of the plurality of 104C, 104D and 104E; and the information defining the allocated portion is provided to the 匣 type memory of the 记忆 type memory that has been allocated capacity. The term "many of the 匣 memory" means that the capacity is independently allocated to each of the plurality of 记忆-type memories up to and including all 匣-type memories.

In one embodiment, a capacity limit is given for each user's jaw memory 104A, 104B, 104C, 104D, and 104E. If the user requires additional capacity, for example, request additional capacity or allocate or purchase additional capacity.

In one embodiment illustrated in Figure 7, the capacity is allocated to the write operation since the read operation is with respect to the previously existing capacity. Beginning at step 202, step 204 determines if the user requests a write operation. The user may include a system, entity or entity or any combination of access to the data storage drive and to the data storage medium. If step 204 determines that the access is different from the write operation (e.g., a read operation), then access is granted for another process. For example, the access may be for a read operation, and in step 206, accessing the user's memory to determine the location on the media of the desired material, and in step 208, performing another An operation.

If step 204 determines that the user requests a write operation, then step 210 accesses the scratch memory assigned to the user to determine the current capacity allocated to the memory and assigned to the user. If the memory is not assigned to the user, then the assignment can be configured.

The capacity of the ports of memory 104A, 104B, 104C, 104D, and 104E assigned to the user may be provided in one of two ways: a logical partition that may be allocated anywhere in the data storage medium; or may serve as An entity partition of an entity-independent area, such as a group of parallel tracks, as defined above.

Step 212 determines if sufficient capacity is allocated to the cartridge and user for the desired write operation or, alternatively, for the desired total capacity allocation. If sufficient capacity allocation has been made and assigned as logical capacity, a particular location of the partition may be obtained in step 214. Step 214 accesses all of the memory to find the free space location of the data storage medium and identify the particular location for the user's write operation or request. Alternatively, the allocation may include one or more physical portions of the capacity, and the meta-memory relay metadata describes the physical partition and step 214 determines the free-space location within the pre-existing entity partition. In step 216, the user performs a write operation and updates the user's memory with the relay data of the location where the data has been stored.

If step 212 indicates that there is not enough capacity allocated to the memory and the user for the requested request (eg, for a write operation), or alternatively, there is no sufficient capacity configured for the requested total capacity allocation, then Step 220 determines if the data storage medium has sufficient remaining capacity available to satisfy the request. If there is not enough remaining capacity available in the data storage medium 105, the process terminates abnormally in step 224.

If step 220 determines that there is sufficient remaining capacity in the data storage medium 105 to satisfy the request, then step 222 assigns the capacity portion of the data storage medium of the data storage to one of the cartridges to satisfy the request. The allocated capacity portion may include one or more logical partitions or one or more physical partitions. In step 222, the user's relay data is updated with information defining the allocated capacity portion. In step 216, the user performs a write operation and updates the user's memory with the relay data of the location of the stored data.
