Abstract

PURPOSE:To write data equivalent to two sectors or more, by writing the prescribed data in the key field of the 1st sector and the blank code in the key fields at the 2nd sector and the proceeding. CONSTITUTION:When the data of 350 bytes is written in case the capacity equivalent to a sector has 256 bytes, the prescribed data is written into the key field KEY1 of the 1st sector with the data equivalent to 256 bytes written into the data field DATA1. At the same time, the blank code is written into the key field KEY2 of the 2nd sector with the data equivalent to the rest 94 bytes written into the data field DATA2 respectively. When reading the data, the field KEY1 of the 1st sector is read but the field KEY2 of the 2nd sector is skipped to not read. Accordingly, a simple write/read is possible for the data equivalent to two sectors or more.
