A perfume-containing controlled release biodegradable resin composition which can release aroma of the included perfume gradually without changing its perfume tone and can be used in such applications as deodorants, etc. The resin composition includes a biodegradable resin which is a random or block copolymer polyester represented by the following formula (1): ##STR1## wherein R.sup.1 is a hydrocarbon radical having 1 to 15 carbon atoms, which is a divalent organic group that may be have a double bond or an oxygen atom but does not have a group represented by the formula ##STR2## wherein the symbol '*' is an asymmetric carbon atom. Each of m and n is 0 or an integer of 100 to 9,000, provided that m+n is within the range of 200 to 10,000. The molar ratio of the structural units [I] and [II] is 1-99:99-1 when m and n are not 0 and the number average molecular weight is 5,000 to 1,000,000, and a perfume such as a cyclic ether, a natural plant perfume, etc., is held in the biodegradable resin.

A method of reading an image recorded in an analog recording medium such as a microfilm and digitally recording the thus read image in a digital recording medium such as an optical disk. The method has independent steps: a step in which command data for allowing the image to be recorded is formed in a command data recording medium such as a floppy disk, and a step in which the image is read from the analog recording medium and recorded in the digital recording medium. With this method, it is possible to digitally record a large quantity of images consecutively at one time.
