Abstract
Abstract A recording medium (1) has a user recordable area in which two types of information may be recorded, such as audio data and user data, and a control area having a first area for management information regarding the first type of information and a second area for management information regarding the second type of information. A reproducing apparatus (10) uses the first management information to reproduce the first type of information and to avoid reproducing the second type of information as the first type of information, and uses the second management information to reproduce the second type of information and to avoid reproducing the first type of information as the second type of information. A recording apparatus (10) generates the first management information when the first type of information is recorded and generates the second management information when the second type of information is recorded.
