摘要： A basic data structure in a lead-in area is made coincident with each other in all of a read only type, write once type, and a rewritable type. The lead-in area is divided into a system lead-in area and a data lead-in area. A track pit and a pit pitch of pits in the system lead-in area are made longer than those in the data lead-in area. In the system lead-in area, a reproduction signal from a bit is detected in accordance with a Level Slice technique, and, in the data lead-in area and data area, a signal is detected in accordance with a PRML technique. In this manner, in any of the read only type, write once type, and rewritable type, there can be provided an information recording medium and an information reproducing apparatus or information recording and reproducing apparatus therefor, capable of a stable reproduction signal from a lead-in area of the write once type recording medium while maintaining format compatibility.

摘要： In order to obtain improved magnetic track density, it is desirable to bring the read and write elements as close to the recording surface as possible, short of actually touching it. This has been achieved by utilizing a magnetostrictive actuator, comprising single or multiple pairs of magnetostrictive elements and their associated conductor coils. A magnetic field is generated by passing electrical current through the conductor coils. This field will saturate the actuator and cause the magnetostrictive elements to contract or expand, thus moving the read/write element whenever so desired.
摘要翻译：为了获得改善的磁道密度，期望使读取和写入元件尽可能靠近记录表面，而不是实际接触它。这已经通过利用包括单对或多对磁致伸缩元件及其相关联的导体线圈的磁致伸缩致动器来实现。通过使电流通过导体线圈产生磁场。该场将使致动器饱和并导致磁致伸缩元件收缩或膨胀，从而在需要时移动读/写元件。
