An object is to effect high quality printing of images such as photographs, designs, and the like, without using special paper. A printing apparatus includes a mechanism for supplying a recording medium that includes a recording medium surface, a mechanism for coating a surface modifier on a surface modification area of the recording medium surface, and a mechanism for drying the surface modifier coated on the surface modification area. The printing information to be printed on the recording medium surfaces includes image information. The mechanism for coating the surface modifier determines an area of the recording medium corresponding to the image information as the surface modification area. An image can be printed on the surface modification area with high quality. The present printing apparatus and method makes possible high quality printing with regular paper, without using expensive special paper, as before.

An information storage medium having both a read-only optical storage portion and a magnetic storage portion that can be written and read is provided. There is also disclosed a drive unit for use with this information storage medium. To control the optical head of this drive unit, a system controller and a CLV servomechanism are provided and form a control portion. When information is written or read to or from the magnetic storage portion, this control portion commands a disk-rotating mechanism to control the magnetic head of the drive unit based on information read from the optical storage portion of the medium. The magnetic storage portion can have either a single track or plural tracks. Interference between the optical head and the magnetic head can be avoided. The drive unit can adapt itself to the information storage medium having the optical storage portion of a large storage capacity and the magnetic storage portion that can be easily rewritten.
