Abstract
An information recording/reproducing device is provided with design features permitting are reduction in device height making it readily suitable for compact utility in a computer assembly, such as, a laptop computer or the like as well as a simplification of parts to provide for a reduction in manufacturing and assembly costs. These features include a structure for miniaturization and simplification of the collet mechanism and its assembly for clamping the recording medium, and the employment of a light guide member in the recording medium detection system for detecting the instantaneous rotational position of the recording medium from which a timing signal is derived. With the improvement of the clamping mechanism and use of a light guide member, significant miniaturization and thinning or reduction in casing height of the device can be achieved. Also, a simple but highly effective locking mechanism, not requiring a separate assemblage of parts, is utilized for preventing the extended carriage arm of the recording/reproducing head from accidentally transferring from its standby position to its operational position in the absence of a recording medium inserted into the information…
