Embodiments can use a model for training according to embodiments of the present disclosure. In some embodiments, a model can be created from actual video. The model can be a spherical video. In this manner, users can be immersed in real situations, and thus the user can get more experience than the user otherwise would have had. Various technical features can be provided for enhancing such a system, e.g., synchronization of pointers on two screens, camera rigs with extended view to allow the camera rig to be placed further from a location of the players, analytics for rating users and controlling playback of a next play (action interval), and for allowing a user to feel translation while in a model.

A computer program product, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and/or executable by a processor to cause the processor to: receive a first portion of data, and divide the first portion of data into a plurality of blocks. An identification segment having identification information therein is appended to each of the blocks, each block and the corresponding identification information appended thereto forming a record. Each record is written in a data partition of the magnetic tape, and an index may be written in the data partition of the magnetic tape. The magnetic tape is rewound to a beginning of tape in response to a final one of the records being written in the magnetic tape, and the index is written in an index partition of the magnetic tape.

Embodiments can use virtual reality (VR) for sports training according to embodiments of the present disclosure. In some embodiments, a VR model can be created from actual video of players. The VR model can be a spherical video. In this manner, players can be immersed in real situations, and thus the player can get more experience than the player otherwise would have had. Various technical features can be provided for enhancing such a system, e.g., synchronization of pointers on two screens, camera rigs with extended view to allow the camera rig to be placed further from a location of the players, analytics for rating players and controlling playback of a next play (action interval), and for allowing a user to feel translation while in a spherical video.

A method for diagnosing problems in tape libraries is disclosed. In one embodiment, such a method includes attaching, to a robot of a tape library, one or more scanning devices to scan internal components and features of the tape library. As the robot moves within the tape library, the method captures, using the one or more scanning devices, three-dimensional (3D) data describing physical locations of the internal features and components. This 3D data is compiled to generate a map of the internal components and features. The method compares the map to a 3D model of the tape library to identify differences between the map and the 3D model. Problems within the tape library may be identified from these differences. A corresponding system and computer program product are also disclosed.

A computer-implemented method for managing a first storage library and a second storage library, according to one embodiment, includes associating a first physical tape and a second physical tape with a logical tape. The associating includes writing a first identifier to an index of the logical tape. The first identifier represents the first physical tape and the first storage library. The associating further includes writing a second identifier to the index of the logical tape. The second identifier represents the second physical tape and the second storage library. The computer-implemented method further includes storing the index of the logical tape in memory, and displaying the logical tape by reading the index from memory as a file system.

A computer-implemented method, according to one embodiment, includes: receiving a first portion of data to be written in a magnetic medium, dividing the first portion of data into a plurality of blocks, appending an identification segment having identification information therein to each of the blocks, wherein each block and the corresponding identification information appended thereto forms a record, writing each record in a data partition of the magnetic medium, and writing an index in the data partition of the magnetic medium in response to a predetermined condition being met, wherein the index is associated with all data on the magnetic medium. Other systems, methods, and computer program products are described in additional embodiments.

An apparatus, method, system, and program product are disclosed for Tape positioning. One method includes identifying a first position on a first tape between a start of the first tape and an end of the first tape. The method includes determining that an access position of the first tape reaches the first position. The method also includes providing an indication indicating that the access position of the first tape has reached the first position.

A system accesses metadata on a file system of the magnetic tape, where the metadata comprising one or more fields enabling to determine a longitudinal position (LPOS) of one or more files located on the magnetic tape. The system determines the LPOS of the one or more files located on the magnetic tape. The system determines an optimal location of the head on the magnetic tape based on computing an average value to the determined LPOS of the one or more files located on the magnetic tape and moves the head on the magnetic tape to the optimal location.

A tape library storage system, keeps track of the identity(ies) of the drive unit(s) that write upon the storage medium of each tape cartridge, and associates the drive unit identity information with the data that each drive writes. The system writes the associated identity information in the tape cartridge memory and/or inserts the information in an index and writes the index on the tape. If a read error occurs when attempting to read data from the tape, the system, by reference to the associated identity information, determines the identity of the original tape drive that had written the data, and transfers the cartridge to the original drive to attempt again to read the data.

A computer-implemented method for unoptimized tape drive read detection is disclosed. The computer-implemented includes determining whether a read order of a trio of related files is consistent with an order in which the trio of related files are stored on a magnetic tape media. The computer-implemented method further includes generating an unoptimized tape drive read warning in response to determining that the read order of the trio of related files is inconsistent with the order in which the trio of related files are stored on the magnetic tape media.
