摘要： A method for checking top and end of tape for data recording and reproducing apparatus is disclosed. The method comprises a first step for sensing a transparent tape section of a start portion of a tape wound about a tape take-up reel so as to sense the tape top. At a second step, a tape supply reel rotation period is detected and the detected supply reel rotation period is compared to a preset value. When the detected supply reel rotation period is not longer than the preset value, the tape end is checked at a predetermined period. However, when the detected supply reel rotation period is longer than the preset value, no tape end is checked. The method makes top-end checking time become optimal and saves power of the recording and reproducing apparatus, and reduces pulse noise generated in turning on or turning off the top-end checking LED.

摘要： A supply reel hub (16) for use on a computer tape drive (10) for assuring that a supply reel (12) is squarely locked down and properly aligned on the computer tape drive (10). The supply hub (16) comprises a locking means in the form of three L-shaped feet (20) for locking the supply reel (12) securely in place, a plurality of spaced apart sensing means (52) and a plurality of signalling means (56,58,60) which sense and signal to a controller (142) whether each of the three L-shaped feet (20) of the locking means (64,66,68) are properly in position. A centering knob (28) positioned on the top of the supply hub (16) has been provided so that a supply reel (12) may be easily centered over the supply hub (16). A groove is positioned on the base of the supply hub (16) to allow a write enable tab to slip off of the supply hub (16) and not hang up on the centering knob (28). Additional sensing means (62,78,86) are provided for sensing whether there is a write enable ring on the supply reel (12). Means for releasably attaching the shaft (24) of the drive motor (27) to the hub base which reduces tape edge damage is also provided. The positioning of the L-shaped feet (20) is checked on loading and unloading and in the event of improper positioning of the L-shaped feet (20), an error message is displayed on the computer tape drive (10) and may also be displayed on the computer. A method of assuring the locking and unlocking of the hub (16) is also disclosed.

摘要： A magnetic tape cartridge (11) comprises a device (16) settable to prevent inadvertent recording and thus erasure on the tape. The device (16) comprises a shaft (21) carrying a control disc (18) intermediate its length. The disc 18 either masks a sensor (23) from a light source (22) or allows illumination of the sensor according to its angular setting. The unit (16) is rotatably mounted in a sleeve (12) formed integrally with a part (11) of the cartridge. The unit (16) has a screwdriver slot (17c) and an indicator (17b). The sensor (23) is connected in a read/ write control circuit.

摘要： A method and apparatus for varying track recording speed to maximize host-to-tape data transfer rates is presented. Variable data transfer rates of host systems and networks are accommodated by continually adjusting the tape speed to match the tape drive to the host's actual transfer rate. The speed of the tape is adjusted according to both the level of data present in the tape drive data buffer and whether the current mode of the drive is write mode or read mode. In the preferred embodiment, when the tape speed is accelerated or decelerated while writing a number of data track pairs to tape, a predetermined number of dummy track pairs are first written to tape at the current speed. On the next write head phase after the speed is increased or decreased as appropriate while the read heads are over the track, a predetermined number of dummy track pairs followed by more data track pairs are written to the tape at the new speed.

摘要： A magnetic tape (10) having a pattern (18) of magnetically polarized stripes (20) recorded thereon. The magnetically polarized stripes are parallel to the length of the tape and are provided on at least one portion (12) of the tape. The stripes are polarized substantially transverse to their length and are recorded to a depth sufficient to ensure that a plurality of data tracks (30) spanning at least a portion of the width of the tape may be recorded over the stripes without significantly altering the magnetic properties of the stripes. The pattern can be used to provide information to a drive, e.g. the type of tape being used, whether the drive has reached the end of the tape, whether the tape is centered, etc. The invention also includes a magnetic head (60,90) for recording the pattern.

摘要： A cassette convey control means (914) can carry a plurality of cassettes, can selectively convey and mount the cassette to a tape driving section, and can feed the mounted cassette outside equipment. A cassette selection setting means (913) and a timer cassette reservation means (1001) output designation data for selecting and designating one of the cassettes. An operation mode input means (916) outputs management data including cassette subsidiary information such as remaining amount display data, or the like corresponding to the designated cassette, or a tape driving instruction. A cassette information storage means (915) can store cassette information (cassette presence/absence information, presence/absence information of a safety lug of each cassette, and the like). A timer controller (1000) and a timer information storage unit (1004) can hold condition information necessary for a timer operation. The timer controller (1000) includes a judgment means for comparing the timer information and the cassette information so as to determine if timer reservation or execution for the designated cassette is possible, and an alarm means for generating an alarm when the judgment result from the judgment means indicates that the timer execution is impossible. A display means (903, 920) identifies a cassette mounted on the tape driving section using an operating cassette display section, and identifies a cassette selected by the cassette selection setting means using a selected cassette display section.
