摘要： A magnetic tape drive in a helical scan system can shorten retry operation time. A data signal reproduced from magnetic tape through reproducing heads is supplied to a regenerative signal processing circuit. If an uncorrectable error is contained in the signal, the regenerative signal processing circuit outputs error information to a system controller. Then, the system controller sends a retry instruction to a movable head controller. When receiving the retry instruction, the movable head controller supplies movable head control signals to displacement elements which then displace the reproducing heads along a rotating shaft of a rotary drum for re-scanning an error occurrence data track. This retry operation is repeated until no error is detected. The magnetic tape is run at lower speed or is stopped as required during the repetitive retry operation.

摘要： A capstanless tape feed control system of a reel-drive type is capable of accurately detecting the respective working radii of a supply reel and a take-up reel and the total length of the tape, of efficiently controlling tape speed and of preventing damage to the tape. The tape feed control system calculates the working radii of the supply reel and the take-up reel and the total length of the tape while the leading end of the tape is moving toward the take-up reel, and detects tape speed on the basis of data representing the total length of the tape and the radius ratio between the supply reel and the take-up reel. The tension of the tape and the reel driving torque are detected while the tape is being fed and the working radii of the supply reel and the take-up reel are calculated on the basis of the tension and the reel driving torque. A tape loading operation and a tape unloading operation are performed after the leading end of the tape has been pulled out from the take-up reel, with the supply reel being held stationary and a predetermined back tension being applied to the tape by the take-up reel.

摘要： A recording/playback apparatus wherein rotary heads play back positional information recorded on a magnetic tape which can travel rapidly in a search operation. Piezoelectric actuators extend the rotary heads, an actuator driver drives the piezoelectric actuators, and a microprocessor controls the actuator driver. A target position on the magnetic tape is designated through a control panel by a user of the apparatus. The processor controls the actuator driver so as to hold the heads out of contact with the tape in a pause or stop mode of the apparatus, and so as to bring the heads into temporary contact with the tape at least once before the tape is caused to travel to the target position, whereupon the processor detects the positional information on the tape. When the target position has been approached, the processor controls the actuator driver so as to hold the heads in contact with the tape, and it detects the positional information. Thus, while providing a rapid search, the apparatus can prevent the heads and the tape from wearing away and can detect the target position precisely.

摘要： In an optical disc drive apparatus, when a start time of a tracking pull-in operation is adjusted according to the eccentricity amount of the optical disc, a suitable starting point of the tracking pull-in operation can be always captured and the pull-in operation of the tracking control can be stably performed, without depending on the eccentricity amount of the optical disc. Further, the eccentricity amount and an eccentricity phase are detected from a track zero crossing signal before the tracking pull-in, and an eccentricity compensation signal of the track is added to the tracking control signal. As a result, also in the optical disc with the large eccentricity amount, the tracking pull-in operation can be stably performed.

摘要： In a conventional method for preventing a collision between a lens and an optical disc which uses a control system similar to the servo control of the optical disc, it is feared that, when there is no need to apply the servo, the collision prevention method may not perform its function satisfactorily. In an optical disc device that operates with a part of its functions suspended for reduced power consumption, the conventional method is not enough to avoid the collision between the lens and the optical disc. By arranging the lens/disc collision prevention mechanism independently operable, it is possible to prevent the collision between the lens and the disc even during the operation with limited functions.
