Abstract
PURPOSE: To make it possible to split and file a series of data on discontinuous tracks by providing a data file part and control data file part on the same track of a magnetic disk and by chaining data.
CONSTITUTION: Track format 41 of magnetic disk 29 consists of data file part 43 where still pictures or sound data are filed, control data file 42 where control data for their chaining is filed and gap 44 between records. Consequently, video signals applied to input terminal 11 are digitized by A/D converter 21 under the control of controller 30 to store still-picture data for one frame in buffer memory 25, and they are also divided and recorded in control data file part 42 and data file part 43 of magnetic disk 29 together with chained information in memory 27 through the switching multiplexer 28, thereby completing files.
