    摘要： A data storage and retrieval system includes a head carriage unit adapted for rotational motion and having multiple heads disposed at a working surface, the head carriage unit adapted for rotational motion. The system also includes a tape drive unit configured to move a tape media past the working surface of the head carriage unit, the tape media having a width approximately equal to a width of the working surface of the head carriage unit. As the head carriage unit rotates and the tape moves past the working surface, a first head is configured to write a data track on the tape and a second head is configured to thereafter read the data track, where data read by the second head is for use in verifying data erasure.

    摘要： Provided are an optical disc recording device and a recording signal generating device which enable to correct displacement between a reproducing position of a reproduction signal from a concave-convex mark preformed in an optical disc, and a recording position of second information to be recorded in synchronism with the reproduction signal, and stably and speedily record the second information. A digital signal processor (202) specifies a reproducing position in the concave-convex mark, using a reproduction signal and a channel clock. A recording signal generator (211) generates a recording signal alternately including a plurality of additionally recordable data, each of which includes second information and has a predetermined length, and a plurality of dummy data. A recording position controller (110) detects a recording position displacement amount representing a displacement amount between the reproducing position and a recording position of the additionally recordable data, using the reproducing position and the reading signal. A recording length adjustor (208) increases or decreases the recording length of dummy data in accordance with the recording position displacement amount.

    摘要： A drawing pulse generating unit of an optical disk recording apparatus judges a bit stream of main data contained in a bit stream signal of frame-formatted data, and generates pulse signals DOTX 1 and DOTX 2 based upon the judgment, and then, outputs the generated pulse signals DOTX 1 and DOTX 2 to the gate circuit. In a time period during which a signal level of the pulse signal DOTX 1 is an “H” level, the gate circuit supplies a bit stream signal of the frame-formatted data to a laser driver. In a time period during which a signal level of the pulse signal DOTX 1 is an “L” level, the gate circuit supplies a bit stream signal indicative of an erase level to the laser driver. The laser driver controls an optical pickup so that a laser light having strength indicative of the bit stream signal is irradiated.
