Media drive, processing method for recording data onto a medium, processing method for data read from a medium, and method for controlling a process for reading data from a medium
View Patent ↗Embodiments of the invention control a recovery procedure effectively in accordance with write conditions. In one embodiment, the data to be written into a sector includes not only user data but also recording condition data, which indicates the temperature prevalent during a write. If a data read is not accurately performed, a recovery procedure is executed. If a data read is accomplished by a retry and the temperature prevalent during a write is lower than predetermined, it is concluded that the employed medium is nondefective. Thus, the read data is rewritten into the same sector without being stored in a spare area. This prevents the spare area from being unnecessarily consumed.
1. A media drive for driving a medium on which data is recorded, comprising
a recording condition data generator configured to generate recording condition data, which indicates conditions for a write onto said medium;
an interface configured to acquire user data;
a write data generator configured to generate write data to be written onto said medium in accordance with said recording condition data and said user data, said write data including said recording condition data; and
a head configured to write said generated write data onto said medium,
further comprising:
a temperature detector configured to detect a temperature,
wherein said recording condition data includes temperature-related information detected by said temperature detector.
2. A media drive for driving a medium on which data is recorded, comprising
a recording condition data generator configured to generate recording condition data, which indicates conditions for a write onto said medium;
an interface configured to acquire user data;
a write data generator configured to generate write data to be written onto said medium in accordance with said recording condition data and said user data, said write data including said recording condition data; and
a head configured to write said generated write data onto said medium,
wherein said head records data onto said medium by allowing a write current to flow to a coil, and wherein said recording condition data includes information about said write current.
3. A media drive for driving a medium on which data is recorded, comprising
a recording condition data generator configured to generate recording condition data, which indicates conditions for a write onto said medium;
an interface configured to acquire user data;
a write data generator configured to generate write data to be written onto said medium in accordance with said recording condition data and said user data; and
a head configured to write said generated write data onto said medium,
further comprising:
a recording condition data acquisition section configured to acquire recording condition data, which indicates the conditions for a write onto said medium, from data read from said medium;
a user data acquisition section configured to acquire user data from said read data; and
a recovery procedure controller configured to control, in accordance with said recording condition data, a recovery procedure for said user data that is performed if data cannot accurately be read from said medium.
