Genre: 3D Polygon Shooting （３Ｄポリゴン・シューティング） First 88706 sectors are correct, the next sector has 1104 bytes of data, then 7508 bytes of zeroes, then it goes data again, but, of course, shifted by 7508 bytes. Therefore, the first 7508 bytes of the audio track also belong to the data track. So the last 68255 sectors of the data track were left scrambled to preserve this anomaly. The 1st pregap sectors (LBA -150 to -1) have the same issue. Technically, the whole CD is mastered incorrectly and defected. A reprint that fixes this masterring error is here.
