(54) DATA ENCODER 

(57)Abstract: 

PURPOSE: To reduce the processing load on a 
microcomputer controlling recording operation. 
CONSTITUTION: Outputs of a synchronizing data 
generation part 51, a cluster counter 52, a sector 
counter 53, a recording data output part 56 and a zero 
data generation part 55 are selected by a selector 57 to 
be outputted. A selector control means 59 switch 
controls the selector 57 at the prescribed timing 
according to a Link signal based on the sector counter 
and a count value of a byte counter 60. Thus, a data 
group (cluster) becoming one recording unit respectively 
constituted of the number of prescribed sectors of a 
prescribed format is outputted from the selector 57.
