An apparatus, system, and method are disclosed for a data storage apparatus with a secondary optical memory. The data storage apparatus includes a data storage cartridge, a primary data storage medium in the data storage cartridge, and a secondary optical storage medium attached to the data storage cartridge. The data storage apparatus, in one embodiment, includes a beam splitter attached to the data storage cartridge. The beam splitter may be positioned at approximately a 45 degree angle in relation to a data storage surface of the secondary optical storage medium.

A rotary switch rotates about an axis which is at acute angles to a lower cartridge surface and a cartridge end so that a first display surface and a second display surface may be independently accessed by disparate components residing in disparate planes. The display surfaces are generally orthogonal to each other and can have multiple facets, with each facet containing a subset of information. To aid this optical interrogation, the display surfaces may be generally orthogonal to the disparate interrogating components.

The recording medium cartridge includes a cartridge case containing a recording medium and a noncontact-type memory having an IC section for storing information and performing signal processing and an antenna section for transmitting and receiving signals. The antenna section of the memory is placed in a region furthest from metallic parts.

A recording medium cartridge includes a memory circuit for storing information concerning signals recorded on the recording medium within the cartridge. The information is stored in the memory circuit in the form of a hierarchic data structure which includes a plurality of data packets having a predetermined form and length. Each data packet includes a code indicative of a level in the data structure to which the data packet belongs. At least some of the data packets include data indicative of starting and ending positions on the recording medium of recorded signals which the data packet represents. The hierarchic (or “tree”) data structure facilitates rapid retrieval and reproduction of the signals recorded on the recording medium, particularly when the recording medium is a magnetic tape. The tree structure also facilitates storage of information in connection with recording of additional signals on the recording medium.

The recording medium cartridge includes a cartridge case containing a recording medium and a noncontact-type memory having an IC section for storing information and performing signal processing and an antenna section for transmitting and receiving signals. In one cartridge, the antenna section of the memory is placed in a region furtherest from metallic parts. In other cartridge, the memory is mounted in an accommodation portion recessed one step relative to a surrounding portion, in such a way that a portion of an inner wall of a real area for accommodating a magnetic tape corresponding to the recording medium is formed, in such a position as to be exposed when the cartridge is loaded into a drive, or in recess formed in an outer surface of a case. The cartridge label is attached to the cartridge and contains the noncontact-type memory. At least an antenna section protective indication for indicating an information writing area other than the area on an antenna coil of the antenna section is provided on the cartridge label.
摘要:
A tape cassette has a housing which contains at least one magnetic tape wound on a tape hub, and a semiconductor memory which contains memory data. The tape cassette also includes at least an optical transmitter, and a circuit which has access to the memory contents and which can read out the memory contents from the memory and embody the memory contents in an optical signal, which is transmitted out of the housing by the optical transmitter. The memory data may characterize data stored on the magnetic tape. The cassette can include a further memory which contains data uniquely identifying the cassette, and this data can also be read out and embodied in optical signals which are transmitted out of the housing. A number of such cassettes can be employed in a cassette library system, having a reader which receives the optical signals and which controls a robotic cassette selector by matching either the memory data or the cassette identification data embodied in the received optical signals to data entered into the reader identifying wanted data or a wanted cassette.
摘要:
A tape cassette of this invention is equipped with a memory capable of accommodating at least management information including identification information unique to each tape cassette. A magnetic tape housed in the tape cassette is written with identification information that is supposed to be the same in content as the memory-stored identification information. When the tape cassette is loaded into a tape drive system, the system acquires both the memory-stored identification information and the tape-stored identification information to determine a match therebetween. A mismatch between the two sets of identification information, if detected, is interpreted to mean that the tape cassette has been tampered with, and read and write operations on the cassette are restricted accordingly. This enhances security against fraudulent uses of the tape drive system.
