McSEIS-1600地震仪磁盘记录格式及数据解编系统

McSIES-1600 Seismograph Disk Format and Converted Data Systen

McSEIS-1600地震仪,把采集到的数据记录在一块双面双密度3.5英寸软磁盘上。磁盘记录格式为:每面80磁道,每盘160磁道,每磁道5扇区,每扇区1024字节,与IBM-PC系列计算机磁盘格式不兼容。记录按炮点目录中的索引地址顺序存放,采集数据按高位在前低位在后存放。这种格式的数据都可在IBM-PC系列计算机上通过用C语言编写的程序修改磁盘参数进行读取,从而对这些数据进行处理。

A data file from seismic record collected by a McSEIS-1600 Seismograph is recorded onto a 3.5-inch double sided, double sensity floppy disk. The disk physical format is 80 tracks per side, 5 sectors per track, 1024 bytes per sector. It is not compatible with the disk format on IBM personal computers, IBM-compatible computer using the DOS operating system. The seismic record is stored sequentially according to the index adress in file directory. The data is stored in high byte first, low byte later and can be read on IBM personal computers through changing disk-base by the program written in c langue, Forward, the data can be processed on IBM personal computers.
