An ink-jet recording head (1) is mounted on a carriage (2), recording engines (3, 3') for printing a recording sheet with ejected ink droplets are so disposed that a recording sheet can be inserted from one of different sheet feed passages (4, 4') and the ink is supplied to each recording engine (3, 3') from a common main tank (6). An ink-jet recorder has a control means (10) for comparing the amount of external print data with a reference amount of data, divides the print data into units of data of one page if the amount of print data is greater than the reference amount of data, and distributes the external print data to the recording engines. If the amount of print data is less than the reference amount of data, one recording engine is operated singly to execute printing.

A multimedia optical disk is provided. The multimedia optical disk includes a data area for storing objects which include moving picture data and at least one of audio data and sub-picture data. The multimedia optical disk also includes an index area for storing reproduction orders of the objects. Route information in the index area includes a sequence of addresses of objects whose alignment represents a reproduction order. Chain control information in the index area corresponds to the route information. The chain control information, being effective in reproducing objects specified by the alignment of the sequence of addresses (objects specified by the alignment of the sequence of addresses are called a chain), instructs the reproduction apparatus to have a navigation control of the chain. A piece of moving picture data having a certain time period is reproduced at the same timing as a piece of audio data and a piece of sub-picture data. A piece of sub-control information, being effective in reproducing moving picture data, sub-picture data, and audio data stored in a small unit instructs the reproduction apparatus to have a navigation control of the data stored in the same small unit.

When a plurality of magneto-optic disks are inserted via a mail slot provided in a front panel block, a controller controls a manipulator of a robotics block so as to load magneto-optic (MO) disks in MO disk arrays constituted by connecting a plurality of MO drives and one Redundant Array of Inexpensive Disk (RAID) controller. Then, when a RAID recording system is selected by the user, the controller controls the recording operation of the MO disk arrays in accordance with the selected recording system. More specifically, when a RAID recording striping system is selected by the user, the controller divides the data supplied from the outside and controls the recording operation of the MO drives so as to perform the recording in parallel by the MO drives. As a result, data such as image data may be handled with a high transfer speed.
