摘要： A recording apparatus for recording digital signals to plural tracks formed sequentially on a tape using plural heads includes a first selector for selecting the first through n track sets, continuous tracks within the plural tracks formed on the tape. A disposer disposes the first through k separated high speed reproduction data areas to the same positions in each of the m tracks comprising the first through n track sets. A first recording unit records the same high speed reproduction data to the same track position in at least the tracks having the same azimuth within the m*k high speed reproduction data areas belonging to the same track set. A second selector selects the n+1 through n+N, each track set comprising M tracks selected from among the tracks to which the high speed reproduction data areas are not disposed. A second disposer disposes a continuous very-high speed reproduction data area to the same position in each of the M tracks forming the n+1 through n+N track sets. A second recorder record the same very-high speed reproduction data to the M very-high speed reproduction data areas belonging to the same track set within the M*N very-high speed reproduction data areas belonging to the n+1 to n+N track sets.

摘要： In a digital signal recording and reproducing apparatus, digital input data is transmitted in a transmission packet format and is recorded in a recording packet format. In a recording stage, an auxiliary signal generator (3) generates an auxiliary signal for special reproduction in the transmission packet format, and the digital and auxiliary signals are converted into respective recording packets by means of recording signal converters (5, 6). Recording means (9, 10) performs a specific recording process on the recording packets and an identification signal for identifying between the recording packets of the digital signal and of the auxiliary signal. While in a reproducing stage, reproduction signal processing means (14, 15) performs a specific reproduction process on the reproduction signal to thereby reconstruct the recording packets and the identification signal. A packet selector (16) detects the reconstructed identification signal to determine whether the recording packet is of the digital signal or of the auxiliary signal, and then the digital signal or auxiliary signal is reconstructed by a signal reconstructor (17) in the transmission format using the selected recording packet, whereby a high quality image output conforming to the transmission format used in the normal reproductions mode is also obtained during the special reproduction modes.

摘要： At least three heads are mounted on a rotary drum. Between the first and third heads which are located in close proximity to each other and have different azimuth angles, a minute height difference is formed in the rotation shaft direction of the rotary drum. Signals of a plurality of data rates are recorded and reproduced by using the first and second heads or the first and third heads. Two heads having the same azimuth angle are disposed on the rotary drum so as to be opposed each other at a central angle of 180°. In search speed reproduction, search data are reproduced by the two heads. Tracks are divided in the unit of plural tracks so as to form track sets. Search data areas of each track set are disposed at a position of each track which is separated from the edge of a tape by a predetermined distance. In search speed reproduction, the phases of the tracks and the heads are controlled, and all effective data of the search data areas are reproduced by plural scans of the heads.

摘要： A signal processing apparatus for changing the frequency characteristics of an input signal, e.g.--a video or audio signal, allows a signal to pass through a transmission circuit in a positive time sequence and then, allows the signal to be transmitted through another transmission circuit having the same transmission characteristics in a reverse time sequence with respect to the positive time sequence. Also, while the transmission circuit is arranged to have a zero-phase characteristic, each segment of a continuous signal is processed throughout a period which is equal to at least two times a duration of an impulse response direction of the transmission circuit. Accordingly, unwanted wave errors appearing at discontinuous regions of the signals are eliminated.

摘要： A 3D volume measuring apparatus using an optical measuring technique performs an accurate measurement by using a common master clock signal to move a slit beam and to perform a measuring operation using the slit beam. An optical sensor has a slit beam source which projects the slit beam onto a surface of an object. A video camera receives an image of the optical cutting line. A master clock pulse generating unit is provided for generating master clock pulses. The slit beam is scanned on the object in synchronization with the master clock pulses. Information of the image of the optical cutting line is obtained in synchronization with the master clock pulses, so that the contour of the vertical section corresponding to the optical cutting line is obtained. A chamber volume correcting method using the 3D volume measuring apparatus is provided in which method an exact cutting depth for a cylinder head can be calculated so that a chamber of the cylinder head has an exact target volume. The cutting depth is determined in accordance with the measured volume of the chamber before a finish machining is performed.
