在磁记录的检出方式上我们提出了用逻辑电路进行峰值位移的校正方法,在同步方式上,根据磁古的机电性能(木以)出了用无峰值位移的外同步记录加以数学锁相环路进行倍频扦补形成同步讯号,在编码方式上将 Reice 码进行简化,并辅之以其它措施,使得在国产 G—3型磁鼓上获得的存贮容量近于国内中型计算机配套的同型磁鼓存贮容量的4倍,取得了显著的 In the detection method of magnetic recording we put forward a logic circuit for peak displacement correction method, in the synchronous mode, according to the magnetic ancient mechanical and electrical properties (wood to) out of the peak-free external sync with the record to be mathematically locked Loop frequency multiplier to form a synchronization signal synchronization, the encoding will be simplified Reice code, supplemented by other measures, making the domestic G-3 drum access to the storage capacity of nearly medium-sized domestic computer supporting The same type of drum storage capacity of 4 times, made remarkable
