Title: Method for controlling writing and reading for magnetic storage medium
Inventor: IGASAKI TOSHIAKI
IPC: G11B20/12
Filed: 1992-08-13
Abstract: PURPOSE:To make reading possible even when an index label area is destroyed by writing the same index information in two index label areas for a writing processing and reading it from one of two areas for the reading processing. CONSTITUTION:When a data writing is finished, the index information of an index information temporary storage area 134 is written in a first index label area 21. Then, if this writing is accurately carried out is confirmed by reading the index information of the area 21 and identifying its coincidence with the content of the area 134. Then, the index information of the area 134 is written into a second index label area 22 and a confirmation is made as the area 21. In the case of the data reading processing, the index information of the area 21 is read into the area 134. When its reading is not accurately carried out, the presence of errors is checked and when no errors are found, a reading is made from a data area 23 based on the index information. When errors are found, its effect is displayed, an operator is instructed to restore an FD and an operation is finished.

Metals, semiconductor oxides or nitrides, such as Si2N3 and SiO2, are usable for the insulating film 4. As a result, the reaction of the ITO film 2 with gaseous hydrogen at the time of formation of the nonlinear resistance film 5 is suppressed. The abnormal growth of the nonlinear resistance film 5 on the ITO surface is obviated in this way and the breakdown voltage increases. The rate of defect generation is lowered and further the intrusion of impurities into the nonlinear resistance film 5 is suppressed. The high reliability is thus obtd.
