Abstract of JP 4172662 (A) 

PURPOSE:To shorten a seeking time by dispersively disposing an alternate sector in a data sector. 
CONSTITUTION:An alternate sector to be replaced with a defective sector generated in a data sector 
after initializing is dispersively disposed in the data sector for storing data. As the alternate sector of the 
defective sector, a nearest alternate sector at the rear of the defective sector is used. If the alternate 
sector is not sufficient, next nearest alternate sector is further sequentially used. Thus, a seeking time 
can be shortened by writing a content of the defective sector in the near alternate sector at the rear of 
the defective sector.
