Abstract: PURPOSE:To attain the high efficiency compression and expansion of a picture by dividing a picture sampled into grid shape into quadrangle areas having (m) picture elements in a right inclined up direction and (n) picture elements in a right inclined down direction, using the (m)X(n) pieces of picture elements as the elements of an (m) row (n) column matrix or an (n) row (m) column matrix, and carrying out a two-dimensional orthogonal transformation. CONSTITUTION:One picture A sampled into the grid shape is divided into rhomboid quadrangle areas A1-A10 having 4 picture elements in the right inclined up direction and 4 picture elements in the right inclined down direction as indicated by a real line and dotted line. One area A4 surrounded by the real line has four picture elements in a right inclined up direction 10 and four picture elements in a right inclined down direction 11, and 16 picture elements in the area A4 are used as a 4 line 4 column matrix [Xij]. Then, DCT transformation coefficients are determined by applying a fourth-order DCT transformation matrix [dij] to the matrix [Xij]. In the same way, the DCT transformation coefficients are determined by using the matrix [dij] for the areas A1-A3 and A5-A10.

Abstract: PURPOSE:To form a hole with high accuracy and with high density with respect to a printing object by comparing a light position detecting signal and a reference position and sending out an alarm signal for an exposure inhibition, when a detected position is shifted from the reference position by a prescribed value or more. CONSTITUTION:Light beams are radiated from each light emitter 13, 14 and 15, and these light beams pass through masks 11, 12 and form an image on the surface of a light receiving element of a photodetector 16. As a result, from each photodetector 16, 17 and 18, a light position detecting signal is outputted, respectively, and sent to a deciding part 21. The deciding part 21 executes a decision by comparing each light position detecting data and each reference position data in a reference part 20. When each light position detecting data is within an allowable range determined by a reference position data, it is decided that the mask 11 and 12 are placed in a coincident position, the device shifts to monitoring of the next exposure again, and when said data is outside of the allowable range, the deciding part 21 sends an alarm signal to an alarm 24, and an alarm for an exposure inhibition is generated.

Title: Magnetooptical recording medium and information reproduction method employing it
Inventor: NISHIMURA NAOKI
IPC: G11B11/10
Filed: 1994-10-24
Abstract: PURPOSE: To enhance the line density of medium by magnetizing a reproduction layer in the direction for stabilizing the information stored in a memory layer when the temperature is lower than a compensation temperature but in one direction through magnetostatic coupling with the memory layer when the temperature is higher than the compensation temperature. CONSTITUTION: In the high temperature region 5 in a light spot 2, a reproduction layer 11 is constantly magnetized in the erasing direction and functions as a rear mask 5. Consequently, the spot 2 is restricted apparently to a region except the high temperature region 5, and other regions serve as an aperture region 3 and thereby a recording domain can be detected at a period shorter than the detection limit. Since a mask can be formed by varying the influence of effective field in the medium, principally the field Hst of magnetostatic coupling force from the memory layer 13, no external field is required. Since the field Hst is proportional to the saturation magnetization Ms2 of the memory layer 13, the saturation magnetization Ms2 is set high enough to sustain stability of recorded information but low enough to cause no reversal of erasure magnetization.  This structure realizes high line density.
