[Object] A cartridge memory according to an embodiment of the present technology is a cartridge memory for a recording medium cartridge, including: a memory unit; and a capacity setting unit. The memory unit has a memory capacity capable of storing management information relating to a second information recording medium configured to be capable of recording information with a second data track number larger than a first data track number. The capacity setting unit is configured to be capable of setting a data storage area limited to a first capacity capable of storing management information relating to a first information recording medium configured to be capable of recording information with the first data track number.

A recording device that generates a hierarchy of groups for classifying each of a plurality of data to be recorded from information on each of the data, and performs a control of recording, for each group of a highest hierarchy, the plurality of data included in the group of the highest hierarchy on a recording medium in a recording order corresponding to an order from the top to the bottom of the hierarchy.

An approach, for storing video data in a plurality of tape media via a ring buffer. A tape data splitter receives video data stored in a ring buffer. The tape data splitter writes the video data to a current tape media. The tape data splitter detects an end of tape media event. The tape data splitter responds to the end of tape media event, by switching the current tape media to a next tape media. The tape data splitter selects a resume point for the video data stored in the ring buffer and writes to the next tape media, the video data stored in the ring buffer that is subsequent to the resume point.

A system and method for the simultaneous creation, assembly and transmission of synchronous multiple personalized messages to specific targeted individuals or other entities. The system can send rich media distinctly personalized messages such as commercials to a small or large group of selected individuals through any appropriate distribution media. A personalized message is created based on segmenting a message into multiple slots, and providing different selectable segments for each slot. The multiple segments are then simultaneously broadcasted over multiple data streams to a receiver, wherein the receiver switches between the data streams to assemble the personalized message in a just-in-time fashion. Other data including overlays, animation, frame transitions etc. may also be transmitted and used to assemble the personalized message.

A magnetic recording medium is provided and including an average thickness t.sub.T satisfies t.sub.T5.5 [m], and a dimensional change amount w in a width direction of the magnetic recording medium with respect to a tension change in a longitudinal direction of the magnetic recording medium satisfies 700 [ppm/N]w.

A cartridge includes a tape-shaped magnetic recording medium and a cartridge memory. The cartridge memory includes a communication unit that communicates with a recording/reproducing device in a state where the cartridge is loaded on the recording/reproducing device; a storage unit; and a control unit that stores information received from the recording/reproducing device through the communication unit in the storage unit, reads the information from the storage unit according to a request from the recording/reproducing device, and transmits the information to the recording/reproducing device through the communication unit. The information includes manufacturing information of the cartridge and adjustment information for adjusting a tension applied to the magnetic recording medium in a longitudinal direction thereof, and the tape-shaped magnetic recording medium has a plurality of servo bands.

A computer program product for writing a servo track includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer. The program instructions cause the computer to monitor a lateral position of a magnetic tape passing over a servo writing head during a servo track writing operation and write servo marks to the magnetic tape. A timing of the writing of each mark is based on the monitored position of the magnetic tape. A computer program product for writing a servo track includes a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computer. The program instructions cause the computer to optically monitor a lateral position of a magnetic tape passing over a servo writing head during a servo track writing operation.

A method comprising: determining, by a tape library, respective tape densities supported by each of a plurality of tape drives and respective tape densities indicated for each of a plurality of tape cartridges; receiving, by the tape library, a command to load a given one of the tape cartridges into a given one of the tape drives; determining, by the tape library, that the indicated tape density for the given tape cartridge matches a tape density supported by the given tape drive; and in response to the determination that the tape densities match, configuring, by the tape library, the given tape drive to initialize the given tape cartridge to the tape density indicated for the given tape cartridge.
